I'm planning to build or buy a new computer that will work with Ubuntu 8.04 perfectly with little effort. I would also like M$ Windows XP compatibility only for high graphic games that emulators can't handle. I found a few systems:

INTEL SIGNATURE SOHO SYSTEM
http://www.pccyber.com/?v=product&i=...URE+SOHO+INTEL

AMD SIGNATURE SOHO SYSTEM
http://www.pccyber.com/?v=product&i=...ATURE+SOHO+AMD

If their is any hardware that you find that may not work in the above systems with Ubuntu, please tell me!
If you recommend a pre-built system I don't want any big brand names like "Dell" or "HP", or anything that comes with Vista.

If it is better to build one myself, please post some good hardware for ubuntu/winxp.

If you can, try to find them on this website: http://www.pccyber.com/

nVidia Graphics cards only, still thinking about either Intel or AMD CPU(please recommend).
