ITX build review / feedback request
Use case is a light gamer, mainly retro/remakes and independent games, Age of Empire 2 DE, the Warcraft III remake, digital versions of board games, replaying old Bullfrog games... Like I say, light. Otherwise I use my PC for watching streaming services, web browsing, ripping CDs, watching DVDs/blurays cause I've gone back to physical media. Fairly light uses.
My current PC is 7 years old. Main motivator for replacing it is reliability. It serves my needs when it is running, but it tends to crash a lot, requires repair and a lot of tinkering. I'd prefer something that just works. Probably over-speccing for the kind of user I am, but frankly components are only gonna get more expensive so I'd rather buy something that lasts a bit.
I'd welcome feedback on any aspect. I'm particularly unsure what to do about cooling in such a physically small build and would welcome advice on that in particular.
