Im 16 and have been wanting to build my own gaming desktop for ages. But just now got serious about saving my money for one. how much do you think i should save up before i can comfortably make one, not including peripherals since i got some thatll get me by for now. Im not worried about putting in the best of the best in it right now since once i make one i can always upgrade it whenever i have some cash, i would definitely want it to run all the newest games though. Also would i be able to clean out a old prebuilt gateway 835gm case and put a gaming rig in that, which would be to cut corners slightly and that would save a bit on a case. I got a hp compaq dc5100 sff desktop but thats way to small, but is there anything i can salvage from that or the 835gm thats worth anything to sell or reuse?
