Hi I was given an old E Mac by a friend . To be honest, it looks really cool, but i dont like the OS. Could I build a pc inside the case of the E Mac? Thanks
It's possible, but you'd have to do all the work, taking measurements, draw up a diagram of where you want everything to fit, and buy only the components that will fit inside it, based on those measurements. Not a great deal we can help you with.
A good place to start might be one of the "Car PC" forums; those guys seem to be very good about knowing what parts fit into what space.
