I had the Asus A7N266-VM and wanted to upgrade to a mobo based off the nforce2 chipset so i could utilize agp8x and 333fsb. I bought the Shuttle MN31N, its the nforce2 igp & mcp-t (integrated gf2mx440, dual vga outputs, integrated nic, soundstorm, ac3 encoding). It does not officially support 400fsb, but one can use softmenu to adjust the fsb to 200mhz.
