I hope it's ok to post this here. I am offering for sale 4 COMPLETE mining rigs including cases, motherboard, RAM, CPU, power supply, and of course, tons of ATI graphics cards.
We built these mining rigs about 6 months ago and have enjoyed running them over the past several months. We are currently moving to a new apartment and unfortunately will not be able to bring them with us due to space concerns.
The timing is kinda crappy for us -- as Bitcoin is back on a strong uptick in value -- but we literally can't take these with us, so we have to sell them. If you've been waiting to get into mining, or if you're looking to expand your operation given the recent Bitcoin uptick in prices, this is perfect for you.
Here is everything that is included:
2x ATI 6970 (Sapphire) - 407-431Mhash/sec
2x ATI 6970 (XFX) - 407-431Mhash/sec
2x ATI 6950 (MSI Twin Frozr) - 428-454Mhash/sec
2x ATI 6950 (HIS IceQ) - 428-454Mhash/sec
2x ATI 6870 (XFX) - 314-340Mhash/sec
1x ATI 6870 (Diamond) - 314-340Mhash/sc
1x ATI 6850 (HIS) - 238-267Mhash/sec
1x ATI 6790 (Sapphire) - 220Mhash/sec
In total, that's 4740-4995Mhash/sec across the 13 video cards!
Since each of the 4 rigs can accommodate 3 GPUs, this allows you to install 12 of these and have 1 as a backup (or for your personal Computer).
Note: all Mhash/sec ranges referenced above are created by taking the range of the 5 highest values reported for that GPU Chipset on https://en.bitcoin.it/wiki/Mining_hardware_comparison
. None of these Mhash/sec values are guaranteed. You are responsible for setting and tweaking all overclocking settings.
1x Antec 100
3x Thermaltake V9 case
All cases are Tower ATX cases with a number of built-in fans.
1x ASUS M5A78L-M
1x Gigabyte GA-880 / GA-880GA-UD3H
1x MSI 870-G45
1x MSI 870U-G55
- 3 PCI Express slots to accomodate 3 GPU card
- CPU already installed
- On-board networking
- RAM already installed
PCI-Express Extension Cables
- All necessary PCI-Express Extension cables are included to install 3 GPUs per machine. We hand-machined these (to cut a notch in the connector) so that they would work with the motherboards and GPUs.
4x 2GB Crucial stick of RAM
All RAM is installed into the motherboards.
4x AMD Sempron 140
All CPUs are installed into the respective motherboards with Cooler Master brand thermal paste.
4x Cooler Master GX-Series 750w Power Supply
These power supplies served us great while we were mining.
We spent well over $6,000 purchasing all this equipment, not to mention the incredible amount of time researching and ensuring that everything would work together. We are looking for $3,999 or best offer for all of the equipment. The only payment method accepted is Bitcoin (convert using current MtGox exchange rate) at the time of delivery/pickup/shipping.
You may pick it the rigs for free from Las Vegas or Los Angeles, or we can deliver them (for a small cost) to Las Vegas or anywhere in Southern California. We could also ship the rigs, but you would be responsible for the full shipping cost, which would probably be a couple hundred bucks.
We are also open to selling the GPUs only, or to selling a portion of the rigs, but we would really prefer to sell everything as a unit, even at a lower price. Let us know in this thread or send us a PM. All serious offers will be considered!
