I made an all-white system for my parents in Florida with this ST62K, a 193p lcd, sony white DVD-RW, wireless Logitech combo, and JBL creature speakers. It looks sweet and works great. I put a 2.8 ghz Northwood in it, seems to be running flawlessly, hope my PSU doesn't "burn up."
Not only does it lack AGP, though, it outputs VGA only (from onboard vid). So, my next upgrade will be a 9250 pci card. I figure that should improve video performance and let me use DVI. BTW, the lcd looks great even with the VGA connection, haven't tried DVI yet though.
This is a great looking little system that does 99% of what most people use computers for with great performance, pretty good for everything but playing the latest games. It is Shuttle's best current answer to the Mac mini IMO, and it came out a year ago.
