My 13 year old son decided to build his own computer so he can play Half-Life Two. He and a friend went on to Newegg.com and ordered parts. Unfortunately, now that they've arrived, they don't fit or work together. Can you help figure out which Intel Pentium 4 processor will work with the Chaintech PT800 VIA SPT800 + VT8237R; Socket 478 ATX M/B; 800 MHz FSB, (2)DDR400; (1)AGP 8X, (5) PCI; (2) SATA 2/Raid 0, 1, (2) ATA133, (1) 10/100Mbps LAN, ( 8) USB2.0; 5.1CH Audio? This is all Greek to me .. I don't know what any of it means. He purchased the Aspire/XDreamer Window 420W case. The DVD-ROM (Lite On SOHD-16P9S BLK DVD-ROM) doesn't match the wire tape thingie in the case. Can you help tell which DVD-ROM will work with that case. He also had a hard time getting the Wintec 512M 3AMD2533-512MI-R RAM stick. Is this the correct one for the Aspire/XDreamer case? Please help this computer illiterate Mom and her frustrated and disappointed 13 year old son.
