I have a cheap Bluetooth controller that works perfectly for me, although to be fair I almost never use a controller so it gets used a couple hours in a month lol. The brand is gamesir and I got it for $20 or so with no issues on Linux using either the Bluetooth mode or the 2.4GHz adapter over the past couple years

Honestly case-wise you just want something you like the look of that fits all your stuff and has some ventilation lol. In your case that’s just checking that it fits an ATX motherboard, the height of your cooler, and the length of your gpu. For your cooler and gpu most mid tower ATX cases will probably fit no problem, so try to narrow things down based on looks/style and having a couple fans (or at least room for them) first and just check dimensions once you’re seriously considering an option. A case that comes with fans is usually cheaper than buying fans separately so that can be a plus for cost savings, but if you’re picky about noise or airflow choosing your own fans lets you optimize for either/both. Different cases will have better or worse cable management options, but if you’re the type to build once for a while and not swap cases or motherboards all the time you may not care too much.

Basically:

1. do you like it?
2. does it have reasonable airflow (more than two fans)?
3. does it fit? (Probably yes if it’s an average sized ATX case)

Looks like a great build, only two recommendations personally:

first, make sure the ram you get is 6000MHz, and in the case of Corsair vengeance they have a CL30 kit and a CL36 for prices that usually aren’t too far apart. If it’s close in price CL30 is better, but if not CL36 isn’t awful (or you could pick up some equivalent CL30 ram for cheaper from gskill or teamgroup).

also someone else already mentioned the SN850X, which would be a great upgrade (2GB/s faster read speeds) but depending on pricing the new sn7100 might be a good middle ground.

Otherwise assuming you slap a decent cooler on there the build looks perfect to me, and the only alternative I’d mention is just that cheaper and similar looking cases exist if you want to cut costs a little to make up for spending more on the ssd (deepcool’s matrexx comes in a mesh version with a similar look to the 4000d at usually half the price with four fans, ime). Have fun with the build!
