It is indeed a sexy form factor, and now with an AGP slot, I'm seriously considering buying one.
The only thing stopping me right now is the promise of an Nforce 2 based model, again with 1 AGP, 1 PCI, but the 5.1 sound and Athlon support instead of Intel.
1 AGP, 1 PCI, a single HD, floppy, and 5.25" bay is all I need for my gaming machine. The burner can go in my other machine, along with extra storage. There's no need to crowd my gaming box. In fact I'm probably better off as far as bogging down my gaming box with non-essential things.
