Ya I seen that m8, it`s sweeet
Not that that needs any adaptation, but u could put a pcb looking backdrop to that - don`t need to be mobos in this case, but if they were part mobos it`d be nice - have a line of like 16 memory slots and occupy them with anything, some old pc133 and badge em with something silly like 8G Fragtek mem-stickers. Make u`r own mock south/nothbridge arrangement, some fake power connectors running in, and strategically light it, make the chips look slightly highlighted (so they standout more than the mobo/pcb). Have a switch that turns the lights on and maybe an led or 4, and some mock fans.
Hehe give it an impression it also works.
