So I want to build a computer, but I don't really have, uh, any experience with computer internals. I've watched quite a few videos on how to build a computer and I'm confident I could do it, but would it be a good idea to pick up some really old computer for cheap somewhere and disassemble/re-assemble it a few times to get comfortable? I don't have all the money I need to build one yet anyway, I'm going to wait til I have $1100-$1200 probably.
