Shuttle AN35N. and let me tell you, it's a POS. i always bought abit before, but after reading all these good reviews on the shuttle i decided that maybe they are good now or something. NO! the bios is crap and it's very unstable. let me put it in numbers: i can only run about 167x11.0=1837mhz out of my 1700+ chip with Corsair XMS (CPUburn stable). in an ABIT NF7-S that my friend has, it ran 210x10.5=2205 like a trooper. im getting that board soon, i need to break at least 2Ghz if im watercooling!
