I did it mostly because my eyesight has gone out the window. Previously I used the tv in the right corner for troubleshooting but the cable from the VR headset didn't reach that far. Yay to getting older :(
Anyway.. I bought the MSI Pro MP165 E6 mobile monitor (cause it has a built-in stand), and the shitty-quality-but-always-seem-to-work Logitech K400 wireless keyboard. At first I tried the Caselabs s8 case but that was too big, so I took the Cooler Master NR200P which fit and had room to spare.
I was a bit worried about heat but it seemed to just work fine however I did add 2 extra fans.
