Day-time re-airs?

[gmknobl]

Personally, I'd go with a small form factor, like something from Shuttle - http://us.shuttle.com/ - just for the desk space and potential quiet if you get fairly good one.

Next up would be something more complicated in a tower with liquid cooling so I wouldn't have fan noise.

SATA is a must now. And you might consider some form of RAID too.

I'm sure you'll have some issues but you'll have fun too!
