I am going to sell my 4x5830 rig pictured in the following forum post: http://forum.bitcoin.org/index.php?topic=7216.msg197453#msg197453
The only change is I am going to swap out the pictured 900W power supply with a 1000W power supply instead.
It has 2 Gig of Ram, and comes with the 4 extender cables from cablesaurus, and a flash drive with linuxcoin loaded.
I have flashed all of the bios's to boot running at 975/300 clock speed. I pull slightly more than 1.2 GHash/sec with my box. I can flash the bios's back to standard though if you prefer.
Anyway, I am willing to help you get set up too if you want me to deliver it. It's pretty easy with Linuxcoin.
I want $1000 for it.
I will post the full specs tonight when I get home from work.
Post or shoot me a PM if you are interested.
