Hello, I am selling custom built mining rigs. They are setup with 6x Radeon 6950. They have windows 7 professional, 40gb sata hard drive, 4gb ddr3 and use ultra efficient 25watt dual core cpus. They use a corsair 850watt power supply for the motherboard and the pcie. They use a 1570 watt dell server power supply for all of the 6pin connectors. Will sell for $2600ea. Currently have 3 on hand. Will have more built over the next few days. I ship them at stock settings and they run at 24-2600khs. They can hash faster if overclocked and shader unlocked. Hosting and maintenance is available for $160 per month ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fs22.postimg.org%2Fdxt7kjlw1%2F20140108_020740.jpg&t=665&c=3b-P6rDyc2ejXA) ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fs28.postimg.org%2Fmt4ne73r1%2F20140108_020732.jpg&t=665&c=1D5VSQgpzLBL0w)

Hosting is an option. I am not charging much more than you would pay for the electricity and the air conditioning.

Possible learning moment for me and free bump to the OP: What does it matter if the GPUs are mix-matched? Should just be a matter of performance? Or.. was the question just to clarify on the specifics of the product advertised?

1. It doesn't look pretty. 2. Different cards have different quality and grade of parts/chips/etc. Mixing them and running at the same speed can give mixed/strange/full moon type results in rare cases. 3. Why would you do that. 4. Cooling is difficult to regulate with different cards. Each manufacturers card and model will run at a different set of clock/mem/thread/etc with different stability and heat results. Tuning and re-tuning these rigs would take three times as long. Most importantly #3.

Most importantly #3. I have a wide assortment of cards, I could probably setup 4-5 machines that have all the same exact cards. I have never had an issue with the miss matched cards, although you did say rare cases. Never had any issue with cooling either, they all run between 72-76. The simple answer to number 3 is availability, they all hash about the same.

The aluminum frames? Yeah I could sell just the frames, I don't have enough material on hand to make an extra frame right now, I only keep enough material on hand for what I have gpus for, but I could have 20-30 ready by the end of next week. I could sell just frames with the studs for the motherboad and screws for around $90, shipping to usa included.

I understand safety margin but still this seems a little overkill is it not? Ignoring non-GPU components that's ~400W per GPU. Also, how efficient is the Dell PSU, as in how much do these draw from the wall?

1224 watts at the wall for the whole machine. Yes they are oversized. I wouldn't build a machine for someone else that wouldn't be good enough for me. Oversizing the power supplies makes them last longer and they run more efficiently. As for the efficiency of the dell supply, It is in the 90% + It has nothing to do with safety, It is about efficiency. Loading a power supply over 80% capacity reduces efficiency by 10-20%

I'm getting 2.1 mh/s from three r9 cards and I put it all in a server case. no custom building case. anyone else doing this?

Most importantly #3. Don't care about #1, #2 rare cases, #3 he's a repair guy, I wouldn't be surprised if some of these cards are refurb/used which wouldn't bother me but should probably be specified, #4 cooling is always a concern and there are many ways to manage. for the OP, thx for the service you provide. you said the $90 for just the case/frame is the cost shipped in the USA? Does that include Alaska? If so... damn, wish I would have waited before I embarked on my PVC project. But I'll def keep you in mind perhaps for future projects. Mind me asking where you get your aluminum and interconnects?
