you can buy a new pc, without monitor, for like $200 bucks. I just gave away my old hp desktop from 2005. it still worked, except the hard drive crashed. it cost me less for a new pc, rather than buy a 1 gig hard drive and windows 7. why would you want to throw good money after bad? the computing world is outdated the day after something comes out. pretty soon your 2005 pc will be obsolete. custom built motherboards? $$$$.
