Hey guys, I would like to build my own computer (sorta). Is it possible to buy a G5 for the tower and update the internals to my own spec. I guess I would like to put in a new hard drive, ram, CPU. I would like to know if this is even possible. I want it to be updated enough to run like a new mac pro but not as powerful as I use it as a personal computer and now a work machine for video/photo editing.
