I'm a PC guy who build my own Windows based PCs from scratch but I'm curious to the whole "Mac thing" and have considered buying a used Mac vs building one from scratch. Even used Macs with reletively slow processors and "average" if not outdated ram, video cards, sound and HDDs sell for alot more on Ebay than what I could build a new state of the art PC for. Anyone build their own Macs? Any reason why not? The only 3 things I see that's different from Windows based PCs (besides the novel Mac cases) is the CPU, motherboard and OS. Otherwise the parts are basically the same. Most of the video cards I see in the used Macs (1-2 yr old Macs)are actually very outdated for the PC world. OK, OK.......I guess not heh? I've searched around at the usual PC supply sites, Pricewatch, Google search, etc and apparently the parts aren't sold separately to the general public. I've opted to buy a used one.
