Hello, I'll be building a computer (hopefully soon). I'll be buying a Mother Board, Proccessor, Hard Drive, and physical memory, all the rest I got. It's actually my dad who is building it (with my assistance). I need to know how I know what motherboard can go with with what processors, etc. My dad proposes that we go to sotre, and by them there so we can check if the two fit. I know though that we can find better deals online, and I know what kinds of stuff I want. I just need to know how I can tell what I can't put together. How can I check?
