This is driving me crazy because I cannot find a clear answer anywhere, so if you know -- PLEASE reply back and help me out. I was wondering if was possible to use my current Intel Celeron 2.50GHz CPU and 60GB HDD from my eMachines, and put it in a new case with a new copy of WinXP, motherboard, 512mb RAM, and new graphics card. (My emachines doesnt have an AGP slot, so i was going to replace the motherboard to get a new graphics card.) Is my CPU and HDD tied into my emachines somehow and impossible to put in a new system, or can it be done? Please reply back! Thanks.
