This case fit my awkward requirements perfectly. Wanted something small enough for my desk but wasn't willing to pay prices I was seeing on itx power supplies, caes and motherboards. So an Matx case with the option to build vertically was ideal. Be aware that in this orientation your motherboard's i/o will be on the underside, so a right angled power cable is a good idea, and if you plug in lots of usb devices, you'll probably want a usb hub so you're not having to fiddle under the case every time you want to plug something in or out. I went air cooled with a Peerless Assassin, and all fans exhaust except the bottom one, hoping that the negative pressure would encourage my gpu to get as much air as possible. Temperatures are good, on par with decent full size cases I've built in. Superb case
I have asus 870i mitx build and 5080 I was using nr200p (which was a huge seller) and my 5080 did fit but left little breathing room. I was aware of need for a bit of space. For this pc there is only a minimal psu frame for larger atx so I stole nr200p psu cage and after one tiny dremel cut it slotted in perfectly, allowed me to keep 850sfx and move to a 360 aio from a 240 and otherwise providing all the space I could wish for. This is a bit smaller than other similar but seems to be perfectly sized for any mitx user who wants a bit more space but wants to retain a smart compact feel. Deepcool should have done better with psu cage choices but otherwise you have a lot you can do here.
