I cant really afford a actual G4, so I decided to make a bare desktop type thing. Here's what I thought: To have a logic board ONLY, add memory to it, connect a externel display,external keyboard/mouse,external disk drive(s),and power adapter. It'd look like a green board with wire sticking out leading to the said additions, in other words. Do I need anything else to add, in terms of technicalities?(not the case parts, actual display,keyboards,I mean do I need some extra board or something?,By the way, I obviously wont need a battery, so no charging boards required. Any hel[p? Thanks!!!
