Been meaning to post about this actually. Will eventually do one but for now you can look at this. It's a Zotac Magnus E51050. Great little box with a mobile GTX1050. The BuyStuffArcade backbox monitor has a VESA mount on the back so I attached the PC directly to the monitor using this VESA mount from HumanCentric.

Forgive the rats nest of wires. Still finalizing modding plans so just leaving it as is.
