I'm curious to see some pictures of those mining rigs.  Share your pictures of your rig and then details of build and mhash/sec.  Let's get a frame of reference up here with some visuals. 

I'm a gamer so this is an older gaming rig (2+ years old now)

A single 4890 that produces 100 mhash.  Bitcoin mining will help me justify putting together a tri or quad video card setup relatively soon.
