lol curtains. building a cmputer isn't hard. for the most part, you can just plug in the stuff in the only place it fits
nepts, just because the motherboard doesn't work doesn't actually mean it was your (or your brothers) fault. it could have just been a defective motherboard.
when i work on my computers, i'm always lying cards, ram, etc on my bed, the rug, a chair, ontop of the pc case, anywhere thats close and without any anti static bags. my hands usually get sweaty too and i'm often dropping screws on the motherboard. hell, half the time i don't even unplug the power cord, i just shut down the pc to make minor changes (like cards or drives). yet after many years, i have had no problems. the stuff isen't as delicate as many people seem to think.
