I have the same exact ASUS mobo. Very nice, indeed. The VIA K8T800 Chipset is awesome...very nForce worthy About the Wireless, you have to buy a special card that plugs into the very last slot...so it's not included (a very handy feature though).
The VIA Nano-ITX motherboard! It's a mere 12cm x 12cm I think someone on techtv (or what not) took apart a Mac Mini and used this motherboard to convert the Mini into a PC. Of course, A-Open now has their new XC-Cube small form factor computers...last I heard, it's even a tid smaller than the Mac Mini And it's a PC
