I've made MSI, Abit, Asus, IWill, FIC, and Shuttle based systems using Celerons, PIII's, Durons, T-Birds and P4's. For some reason I've had bad luck with the Abit boards. Right now my wife is using my Shuttle AK31A/XP1600+ system and my system is an Asus P4S533/1.6A (running at 2.24Ghz). I love the Asus system...fast, stable, lots of tweaks in the BIOS.
