If I did mine with it myself instead of hosting, a few things come to mind.

What do you guys plan on using for a case? I have 1 64 chip board. I might just build something.

What do you plan on using for cooling?

I might use a small house fan.

9 inch should do it.

I have an old netbook (n280, 2 gigs of ram, ocz ssd)

Is a netbook appropriate for the job? I'd let the screen sleep, but never the netbook itself.

It's only wireless G, though I do have a wireless N network, with a 50 megabit down, 10 megabit up connection.

I wonder if I could hide it at work somewhere
