When I think of a gaming PC, I just think of my Original Xbox-since that's what it actually is. x86 Pentium III-check, Nvidia dGPU with dedicated vRAM-check, system memory-check, hard drive-check, optical drive-check, ATX compatible (on the consoles I've worked on) motherboard-check-----Yep the Xbox Original is a PC and can even use a keyboard since it has 4x USB ports (with a custom connector that needs an adaptor yes-but they are USB ports).
Edit: Also, the Xbox uses high quality components such as rubycon electrolytic capacitors and solid capacitors which I haven't identified yet-which can't be said for its 'successors'. (The Xbone isn't as much of a console-and its built to be dirt cheap)
Personally I'm a bit of a Logitech fan when it comes to peripherals, mainly because at least in my region, Australia they're a bit cheaper than the competition and I've never had anything of theirs be anything less than great quality.
