Peter-- Let me know when you start putting these together. I'll be more than happy to help out with assembly (and in home testing). Hell, I'll shave and try my hat at selling them too!
I think austin has some great ideas as well. The only thing I'd add is make the ethernet port 10/100/1000 since gigabit hubs are getting cheaper and cheaper...

Gee I miss having 5 pcs networked at home....
