It took a long time but i found a Mother Board that will fit in the NES case + some room to put more stuff.

"Measuring just 170mm x 170mm, the VIA EPIA Mini-ITX motherboard is 30% smaller than the smallest Flex-ATX platforms, while maintaining Micro ATX chassis compliancy. The VIA Apollo PLE133 North Bridge features integrated graphics with 2D/3D acceleration and DVD Motion Compensation, accompanied by onboard SoundBlaster™ and SoundBlaster™ Pro compatible audio, delivering key multimedia capabilities. Onboard 10/100 LAN, TV-Out, an additional PCI slot, and a full set of I/O features provide ample connectivity and expansion options."

I am going to buy the case for the ITX power supply because you cant get that on its own.
