Selling 2 Scrypt mining rigs using Sapphire 280x Toxic and 290x Tri-X

I'm selling two rigs I built. Because of the frame, they are built together into one large section, but will be disassembled prior to shipping.

All GPUs are on 16x powered risers. Both rigs hash with very low error rates. I have also babied all of the cards, with none of them getting over 80C.

Rig 1 - 3MH/s unoptimized (3.75MH/s with additional GPU) - $4500
4x Sapphire R9 280x toxic (750kh/s stock)
1x extra Sapphire R9 280x toxic with powered riser
1x 1600w LEPA gold rated Modular power supply
1x 750w gold rated bnon-modular power supply
1x Gigabyte 990FXA-UD7 Motherboard
Runs at about 78C, less with a box fan

Rig 2 - 4.5MH/s unoptimized (5.4MH/s with additional GPU) - $6500
5X Sapphire R9 290x Tri-X (900kh/s stock)
1x extra Sapphire R9 290x Tri-X with powered riser
2x 1200W modular power supplies
1x Gigabyte 990FXA-UD7 Motherboard
Runs at about 75C, less with a box fan

I never got around to installing the two additional cards I bought, and I can't spend the time to keep working on these. I need to double check that I have the boxes the first rig came in, but I know I do for the second one.

Both are happily hashing at a combined total of about 7.5MH/s (9.15MH/s with new cards).

Trusted escrow accepted and encouraged (Anyone want to escrow for this?). These are located in MA, USA, but can ship to anywhere if you pay shipping.

I will include pics later after I get home. Prices are also negotiable.
