Anyone built a mini ITX system recently, was the size worth the hassle?

[Quanta]

Something I have been researching and wanted a sanity check on.

Real answers from people here are usually more useful than search results.

I have done the obvious searches and got the usual recycled answers so thought I would ask here instead.

What has your experience been?

[QuantumKnight]

Been reading the same thing from a few different angles. Curious to see how this develops

Basically my experience exactly. Task Manager tells you most of what you need to know if you know which columns to look at.

Happy to help further if you get stuck

That is about where I am at. Would recommend giving it a go

Yeah that is about right. Cheers for sharing.

[VB]

Pretty decent summary of it. Worth a try if you get the chance.

[RedKnight]

That is about where I am at. Would recommend giving it a go.

I would push back on that hard. Time will tell on this one

[RedKnight]

No real argument from me on that. Management makes as much difference as the players at this level.

The result will answer the question better than any of us can.

[KnotKnull]

Not bad at all. Worth a look if you have not already

[John]

Makes sense. Could not agree more.

Cheers.

[MayanHan]

The initial reporting on this was all over the place. Curious to see how this develops

[Jeffy]

I don't know, I had a different experience. Good shout

[Tracey]

That is about where I am at. Would recommend giving it a go.

I would push back on that hard. Time will tell on this one.

I tried that and the catch was not obvious until afterwards. Cheers for sharing that

[StoneCold]

That is the obvious answer but not always the right one. The thing that actually helped me was checking what changed just before the problem started.

Worked for me at least

[StuckOnDestiny]

I love the way you put that. Really good thread this

[Hollow85]

That is the sensible route. Take your time with it and it will come out well

[Pilgrim]

Makes sense. Could not agree more. Cheers.

That is a popular opinion but I think it is wrong. Experience in big games counts for a huge amount and younger squads often find that out the hard way.

Cannot wait for the game to settle it

[Golden Tara]

Completely agree, and it is frustrating that this is not more widely known. That is the sensible starting point

[Undertaker92]

I tried that and the catch was not obvious until afterwards. The best deals are usually the ones that do not get advertised loudly.

Worth a look if you have not already.

I loved the idea of mini ITX more than the reality. Building it was fun for about 3 hours, then I started questioning my life choices while trying to plug in the front panel headers.

It does look amazing on a desk though, like a little tech sculpture

[Coder65]

For me it was absolutely worth it because I move house a lot. Having a compact system I can just grab and go is a huge advantage.

I will never go back to a massive tower unless I suddenly win the lottery and decide I need a server rack in my living room

[Warden]

I went mini ITX and regretted it slightly, not because of performance but because upgrade flexibility is basically gone. Everything is so tight that swapping parts feels like surgery.

If you are the type who likes to tinker often, I would say think twice before committing

[Hannah56]

Cooling is the part nobody talks about enough. You can have the best CPU and GPU but if airflow is bad in a mini ITX case, you are basically building a toaster.

I learned that the hard way with my first build

[Wandering Matt]

Cable management in mini ITX is either a satisfying puzzle or pure chaos depending on your patience level.

Mine started as a neat build and slowly turned into "as long as it closes, I am happy" territory

[IronFist38]

I think mini ITX makes the most sense for mid range builds rather than high end monsters. Once you start pushing top tier GPUs, thermals and space become a real headache.

Still, I respect anyone who manages a quiet and powerful ITX setup because it takes planning

[ProperJobs89]

I previously built a mini ITX system about 6 months ago and honestly the size was absolutely worth it for me. Having a full gaming capable PC that basically disappears on my desk is still kind of amazing.

That said, the build process was way more fiddly than a standard ATX case. Cable management in tight spaces is a whole different sport

[alwaysPatrick19]

Mine ended up being a hybrid compromise. Small case, but not the absolute tiniest ITX form factor. That extra 2 or 3 liters makes a surprising difference for airflow and sanity.

I think people underestimate how much thermal management changes when you shrink everything down

[NorthernKernel]

I went full ITX because I wanted a clean desk setup and no regrets there. It just looks so much more modern than a giant tower under the desk.

But I will admit I miss having room to just add drives and cards without thinking about space constraints

[CobyOlaleye]

Would I do it again? Yes, but only with careful part selection from the start. The planning stage matters way more than with bigger cases.

If you rush it, you end up with regrets and a case that looks like it is fighting for its life

[Western Depot]

I think people overhype the difficulty a bit. Yes it's tighter, but if you plan your parts properly it is not that bad.

The real issue is when people try to reuse random old components and expect them to magically fit in a tiny case

[CosmicRay67]

Honestly the price premium on mini ITX parts is what annoyed me more than the size. Smaller motherboard, smaller case, somehow still more expensive.

Feels like you are paying extra for the privilege of less room to work with

[Gary98]

Built a mini ITX machine last year and the size ended up being the thing I liked most about it. The extra planning was annoying during the build, but once it was sitting on the desk taking up hardly any space, it felt worth it.

The tricky part is not the size itself, it is the order of installation and choosing parts carefully. With a normal case you can be lazy and fix mistakes later. In a tiny case, every cable and component suddenly has an opinion

Would I recommend it to everyone? Probably not. For someone who upgrades constantly, a larger case is much easier to live with.

[Merchant89]

The price premium is a fair complaint. It is funny that smaller often means more expensive when manufacturing is supposed to reward compact designs.

A lot of the extra cost comes from specialised parts though. Mini ITX boards, small power supplies, and compact coolers all have smaller markets, so the savings never really appear.

For me the appeal is more about the final result. A clean little system that disappears into the room can be more satisfying than a giant tower full of empty space.

[Di87]

Had a mini ITX build that started as a practical idea and turned into a puzzle game. Spent more time checking measurements than actually choosing performance parts

The cooling side is where people underestimate things. A small case can handle powerful hardware, but airflow planning matters a lot more. A bad layout will punish you quickly.

Still, there is something satisfying about getting a full desktop PC into a space where people expect a console. The compromise is real, but so is the charm.

[Theo90]

The best question is probably whether the size solves a problem for you. If the PC needs to fit somewhere specific, mini ITX makes a lot of sense.

If the goal is just having a smaller computer because it sounds cool, the extra cost and reduced upgrade options might get frustrating after a while.

That said, building one is a fun experience. Sometimes the challenge is part of the reason people do it in the first place. Just keep a screwdriver handy and prepare for some cable wrestling

[SignalMage]

Built a mini ITX machine last year and the size has been brilliant for my desk. It is nice having a proper desktop that does not dominate the room like a small fridge with RGB lights attached

The annoying part is that every upgrade becomes a little puzzle. Cable management takes patience, cooling choices matter more, and you cannot just throw in any random graphics card without checking measurements first.

For me the trade-off was worth it because I move the PC around occasionally. If it was sitting under a desk forever, a normal mid tower would probably have saved money and headaches.

[DecisionNode]

The funny thing about mini ITX is that you pay extra to make your life more difficult, then tell yourself it was worth it because the final build looks great. A strange hobby when you think about it

That said, there is something satisfying about fitting everything into a tiny case and still getting full desktop performance. The first boot feels like a magic trick when you remember how little space everything has.

The main advice would be planning the build before buying parts. A cheaper motherboard, smaller case or wrong cooler choice can turn the whole thing into a very expensive game of Tetris.

[BretHart]

Mini ITX builds are a bit like owning a sports car. They look great, they are fun, and then occasionally you remember practicality exists for a reason

The price premium is probably the biggest downside. Smaller parts and specialised cases can cost more than standard options, which feels backwards until you see how much engineering goes into fitting everything together.

Still, there is a market for them. A compact gaming PC in a living room or a clean workspace setup makes a lot of sense. Just do not expect it to be the easiest route if you enjoy constantly swapping components.

[Marcus95]

Went from a big tower to mini ITX mainly because I wanted more room on the desk, and the difference was bigger than expected. The PC became part of the setup instead of the giant box hiding underneath it.

There are still compromises though. Some cases are great to look at but feel like they were designed by someone who hates hands. Trying to connect one cable in a cramped corner can become a full afternoon activity

Would not recommend it for everyone, but if the size matters to you then it can be a really rewarding build. Just do the research first because tiny cases have zero mercy for mistakes.

[Isabella_61]

My build was mostly motivated by moving house. The new desk area was smaller, and the old tower was awkward enough that it ended up on the floor beside the desk where it collected dust.

The ITX case sits neatly on a shelf beside the monitor and looks much more intentional. That alone made the change worthwhile for me.

Building it was definitely slower than assembling a conventional tower. There were a few moments where I had to remove something just to reach a screw I had forgotten to tighten earlier.

But once it was finished, the inconvenience disappeared. You do not think about the ten minutes you spent fighting a cable every time you sit down to use the PC.

If space is genuinely limited, I would say give ITX a serious look. If space is not an issue, there is no prize for making your life harder for the sake of a smaller box.

[GoldDriver]

A friend built an ITX system specifically because he wanted to put it in a cupboard, which is where I would draw the line. Compact does not mean it should be stuffed into an enclosed space with no airflow!

The case itself can be tiny, but it still needs somewhere to get cool air from and somewhere to dump hot air. That becomes even more important when you are running a decent GPU.

Mine sits on top of the desk instead. It gets plenty of airflow, is easy to reach and does not collect nearly as much dust as the old tower did under the desk.

That placement also makes the size feel more worthwhile. You can actually see the compact case rather than saving a few centimetres under the desk that nobody notices.

Small form factor is great, but basic physics still gets a vote.

[Violet16]

The desk-space argument is stronger than I expected. Went from a full tower to a compact ITX case and suddenly there was room for a larger mouse mat, speakers and a notebook without everything feeling squeezed together.

That sounds trivial, but if you spend several hours at the desk every day, the physical footprint matters. The computer does not need to be the biggest object in the room.

There is also the portability factor. Mine is not exactly a laptop, but moving it between rooms is easy. Taking it to a friend's house for a gaming weekend is realistic rather than an operation involving straps and a second person.

The downside is that small cases can make maintenance less pleasant. Cleaning dust filters or replacing a component can involve removing several panels first.

So was the size worth the hassle? For me, yes. For someone with a huge desk and no reason to move the machine, a conventional mid tower is probably simpler and cheaper.

[NightCrawler81]

There is a bit of a misconception that mini ITX automatically means compromising on performance. It really depends on the case and what hardware you choose.

A reasonably sized ITX case can take a surprisingly powerful CPU and graphics card. The compromise tends to be cooling, noise and how much effort you have to put into getting airflow right rather than raw performance.

Where it gets annoying is storage. You can obviously use NVMe drives and high-capacity SSDs, but if someone wants several 3.5-inch drives, an ITX build stops being particularly attractive very quickly.

For a gaming machine with one or two SSDs, though, it can be a great fit. The system I built has been sitting beside my monitor for months and I still appreciate not having a huge box underneath the desk.

Would I build ITX for a workstation with loads of drives and expansion cards? Probably not. For a compact gaming or general-purpose PC, the advantages are much easier to justify.

[NeonPhantom]

There is definitely a psychological benefit to having a smaller machine. My old tower made the desk feel like a workstation even when I was just browsing the web. The ITX build looks much less imposing.

Performance-wise, the difference has been basically invisible for my normal workload. Games run well, Photoshop is fine and general desktop stuff obviously does not care whether the motherboard is ATX or ITX.

The biggest practical difference is expansion. There are fewer slots and less room for adding specialist cards, so anyone planning capture cards, sound cards or lots of networking hardware should think twice.

Wi-Fi and Bluetooth built into most ITX boards can cover a lot of everyday needs, though, so the lack of expansion has not bothered me.

It is one of those cases where knowing what you actually use matters more than what you might theoretically want someday.

[LunarShade65]

For a first build, I would probably recommend something slightly larger than the absolute smallest ITX case. There is a sweet spot where the computer is still genuinely compact but you do not need tweezers to install an SSD.

My current case is technically ITX, but it has enough room that I can reach most components without dismantling the entire machine. That has made upgrades much less intimidating.

The temptation with small form factor builds is to keep chasing the smallest possible volume. At some point, saving another few litres is not worth making every future repair a project.

A compact case under the desk can already give you most of the practical benefit. You do not necessarily need something that looks like a particularly ambitious router.

So I would start with the footprint you actually need, then work backwards from that. The smallest possible PC is not automatically the best small PC.

[Sophie83]

Built a mini ITX machine last year and the size was absolutely worth it for my setup. The desk is in a small spare room, so losing a big tower made the whole area feel less cramped straight away.

The catch is that you really do need to plan the parts before ordering anything. With a normal ATX case, there is usually some room to improvise. In ITX, one cable in the wrong place can turn a ten-minute assembly job into an evening of swearing.

Cooling was the part I spent most time thinking about. The final build used a sensible power limit on the CPU rather than trying to squeeze every last bit of performance out of it, and temperatures were much easier to live with.

For me, the best part is that it still feels like a proper desktop. It is fast, upgradeable and easy enough to move around, but it does not dominate the room. That trade-off made sense for my use case.

[VoidSentinel66]

One unexpected advantage was moving the PC around while decorating. Normally you realise just how heavy a gaming tower is when you have to lift it onto another desk. The ITX machine is much easier to pick up with one hand.

That also makes cleaning easier. I can take the whole thing outside, remove the panels and blow the dust out without feeling like I am relocating a piece of office furniture.

The downside is that every component becomes part of the thermal puzzle. You cannot just add another case fan somewhere and hope for the best. Airflow paths matter much more.

Still, after a bit of tweaking, temperatures have been perfectly reasonable. The system is not silent, but neither was my old tower.

For me, the compact footprint and portability have outweighed the fiddly assembly. It feels like a proper desktop that happens to be easy to move, which is a pretty nice combination.

[Coder22]

The most annoying part for me was motherboard connectivity. My old ATX board had a ridiculous number of USB ports and headers, and the ITX replacement obviously had less room for all that.

At first I thought it would be a problem, but a decent powered USB hub solved most of it. Keyboard, mouse, controller, headset and external drive are easy enough to manage.

The important thing is to count your actual devices rather than looking at the specification and assuming you need every port available. Most people probably do not use half of them regularly.

The same goes for PCIe slots. If you need multiple expansion cards, ITX can become restrictive very quickly. If everything you need is already on the motherboard, it is much less of an issue.

That is probably the general theme with ITX: decide what matters to you first, then accept that some flexibility has been traded for the smaller footprint.

[Sharon_77]

One thing worth mentioning is noise. People tend to focus on whether everything physically fits, but a compact case can get noticeably louder if the fans have to work harder.

My first setup was a bit too ambitious with the CPU and GPU combination. It ran perfectly well, but under a long gaming session the fans became very enthusiastic. Not dangerous, just impossible to ignore.

After tweaking the fan curves and putting a sensible power limit on the GPU, it became much nicer. Performance barely changed in the games I actually play, while the noise dropped considerably.

That is probably the lesson I would pass on: do not build a tiny computer around benchmark numbers alone. Choose hardware that makes sense for the thermal volume you have.

A quiet compact PC is lovely. A tiny PC that sounds like it is preparing for takeoff every time you open a game is considerably less charming.
