I had a client that replaced his HP for a Bigger, Better, Faster computer,and he was going to throw the old machine out?! I told him "I'll take it!" Then put in a New Mobo, so I did what T_T did, but put an ASUS MOBO in, with an AMD 64 Quad Core, a 500 Gb d-drive, and a Solid State C: Primary Master, along with DDR3 memory, and a Nvidia video card. This thing screams, and there was "NO" modifications needed to the case! I did a "similar" update to another clients old Micron (those cases were tripple fanned, made of thick steel, andRFI insulated on all sides! The original mobo is a good idea, but "I have a Need for Speed!"
