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

I'm sure doing all the above will work fine,,,maybe not hiding it at work tho...lol
