I'm not really big into emulation. The only emulator I've purchased was the Amiga Forever 4.0 a while back. Although i really do not use it as a full fledged Amiga from day to day, just tinkering around with it whenever I get a chance.
My local PC shop sells a cube type system with integrated everything plus an AGP slot. Has an Intel and AMD model CDRW and floppy and the cube has a handle on it. I'll see if I can get the mobo info next time I'm in there.
