Just my 2 cents: If you don't need RAID, you might want to consider one of the SDR/DDR motherboard solutions rather than a KT133 solution. With a SDR/DDR solution, you get the best of both worlds - you can use your SDR RAM now, and switch to DDR later for better performance if you want to. I just upgraded to the system shown in my signature, and am very happy so far. I looked at KT133a motherboards before upgrading, and most were over TWICE the price of the two available SDR/DDR motherboards (Shuttle AK32 and ECS K7S5A). Just doesn't seem to make sense buying old technology.
