Shuttle ST61G4. This could very well be the perfect Intel-based small form factor machine. Has a very fast ATI Radeon integrated graphics chipset (about half the speed of their top of the line card, which costs more than the entire Shuttle box!)
Also has silencing technology to be quiet as well as a 6-in-1 card readers. Wow! Perfect as the Intel Pentiums are about to fall in price in the next couple of months.
