I'm selling my 6 card 5830 riggs for 75 btc a piece.
I already had them sold and set up in their server room, but the buyer didn't understand the power consumption or cooling so it back to the market for all of them.

My cost:
6x 5830 = 720
6x PCI-E risers = 66
1x GD70 = 145
1x Semplon 140 = 45
1x 2gb Kinston ddr2 = 15
2x Thermaltake Bronze 750watt PSU's = 180
1x custom light bulb psu load =10
1x 2gb USB Flash Drive = 5

My Total = $1186 + shipping

Ill let them go for 75BTC shipped, that's 1005USD at 13.4
72 for local pickup, Southern California.

[140 shipped]

We're opening our doors with 2 sweet items!

-------------------------------------------------------------------------------------

"Like" new but guaranteed working Sapphire 1GB 5830's for 140 shipped to anywhere in the United States.
Bulk discounts are available upon request and verification of identity.

Max use has been 2 weeks but most have never been used, the boxes are open though so we cannot sell them as new.
None have been overclocked or bios modded.

We will also mod and run stability tests on the cards for a fee of 10$ each but this is completely optional.
None have been modified so they must be stress-tested and this will take some time.
Gain would be from 240-250 mhash starting to 300-320 mhash and would have a 1-2 day delay on shipping.

----------------------------------------------------------------------

Also we are selling a limited amount of 6 card 5830 mining setups for $1500+ shipping (next day once shipped at ground rates) which gets 1400-1500 mhash with no overclocking and pulls around 1000 watts exactly.
It also comes with linuxcoin preloaded booting to a self sustaining script with heat saftey and gpu load monitoring built in that will pull the current pool from a web address.

6x Sapphire 5830 1GB Gpu's
6x PCI risers 1x or 16x variety, all cards will work the same with any combination.
1x MSI 890FXA-GD65 AMD Motherboard
1x 2GB standard Kingston ram
1x Sempron 130 AMD CPU
2x 750 watt Thermaltake bronze 80 PSU's
1x belkin power strip
