Working on a Mini-ITX build for the first time, looking for advice on the build / part suggestions for the European market (my first time building in the EU, 4th PC build).

Budget: €2250 (preferably lower, open to buying some parts used / waiting for sales)

Current part mix: https://pcpartpicker.com/list/KwGW9K

Use: Primarily gaming, the ethos is I'm trying to get the Steam Machine that I really wanted with AM5 and RDNA4. Not trying to hit actual Steam Machine targets / budget. Will put Steam OS on it.

Fun other things: If people have suggestions on HDMI-CEC or getting a Steam Controller to turn on the machine, I'm all ears.

Open questions:

  • Any suggestions on CPU / GPU mix to hit 4K 60 with minimal FSR?
  • Any thoughts on keeping it quiet, since this will be next to my TV?
  • Any tips on actually doing a Mini-ITX build?

If you're doing mini-ITX as opposed to the more-common ATX, it's presumably for a reason. You might want to list a rationale, since it'd help people make suggestions, as there are different reasons someone might want to go down that path.

Like, a while back, I was looking into doing a mini-ITX build because I wanted a machine that I could lug around as a laptop alternative. For that, being small in volume (even relative to typical mini-ITX systems) and durable is important.

A different person might want a cheaper case. Or just to use less desk space.

Any thoughts on keeping it quiet, since this will be next to my TV?

I looked into this a while back. Very quiet builds are kinda restrictive (especially for gaming systems).

You may have luck just putting it in a (ventilated in the rear) cabinet. Maybe stick some sound-absorbent foam on the inside.

Or just move the PC elsewhere, if you can run an HDMI cable to your TV and a USB cable for input devices into the room. You can get (pricy, stiffer) cables with more shielding, or (also pricy) ones with fiber optic cable inside and a transceiver at each end that permit for much-longer-than-normal cable runs, if you can't manage it with regular cables.

Fair. I'm thinking about a mini-ITX build partially for the fun of it, partially because space is at a premium in my setup. I don't need to move this around much, but do care about the design a bit.

Otherwise, fair points on the sound management. I don't think it needs to be super quiet, but relative to a PS5 at full blast, thinking that's the sound limit.

You might be able to find a compromise in M-ATX form factor.

Smaller than normal ATX, but less of a price premium than ITX, easier to find ... spatially compatible higher end GPUs, and people do make more compact M-ATX cases.

EATX, ATX, MATX, ITX.

Now your taste in cases may be different than mine, and I've no idea what EU prices look like, but...

Asus Prime AP201

Jonsbo D30

ThermalTake Tower 300

... if you want to be a bit of a show off, haha.
