Binky, I don't trust System OEMs, like Dell. These companies pawn off junk to unsuspecting consumers, as Consumer PCs, and, these are not upgradable. Chaintech has been around a while, and is a respected motherboard manufacturer. PC architecture is Open Architecture. Besides, in building your own, you can select very high quality parts. Also, the real benefit of building your own Standards Compliant PC, is that you know everything that is inside it, and you don't need to depend on expensive, and sometimes useless phone support.
LukeK, I am also looking at VMWare, which is less expensive than I thought. If that can do more than 128 MB per session, then it will be a better alternative than Win4lin.
