The biggest expense though was the >memory. around 4 thousand if i remember right WHAT?!? Last April, I paid $330 for 1 GB Reg/ECC pc2100 CL 3 ram. Prices have not risen -that- much. With 4 slots, that means I get up to 4 GB. I actually only get 3.5-3.8 GB with 4 1 GB DIMMs because of memory-mapped I/O. (Whether this is a limitation of the AMD chipset, the Athlon, or the hardware I do not know. I think it is likely that the Pentium 4 Xeon systems have similar limitations.) -Matt
