Unlike traditional banking where clients have only a few account numbers, with Bitcoin people can create an unlimited number of accounts (addresses). This can be used to easily track payments, and it improves anonymity.

Here's our 7 card 290x monster rig from Ninja Group Buy #4. It's a rack mounted tray design meant for deployment into a data center cabinet. What are the temps like with so little airflow between the cards?

I'm also working on a 4U rackable case for data center hosting, but I've doubts about temp and ventilation. I'll post pics of our prototype tomorrow. Could you please post hash rate and temperature, when multiple cases are enclosed in a 19" rack?

Could you please post hash rate and temperature, when multiple cases are enclosed in a 19" rack? With a box fan sitting on top of the cards they stay around 75C, pulling 930kh/s each. They are scheduled to be installed into our rack later this week, and we'll sort out their airflow/cooling situation then. This one is going on the bottom rack of one of our cabinets; with 2 airtiles popped right in front of it. If I were to do a full cabinet worth I would go with max 6 per 4/5U case, enclose them and pressurize the case with high CFM server fans. This is all highly experimental of course (and fun!). I'll post an update later this week after they move to their permanent home.

With such easy access to the needed power, is there any particular reason you aren't using server power supplies for the cards? If you ever need help with custom rackmount cases, let me know

If you ever need help with custom rackmount cases, let me know We had the corsair 1200's on hand; we've been looking at server power supplies and having some custom cables made up to provide a ton of pci-e plugs. I found some on taobao done up like that and they are very cost effective.

Pretty much the same as me, I picked up a few big EVGA supplies before they got expensive, luckily. Been working on putting together the server supplies lately, about tired of crimping after one rigs worth of cables already. I've been de-pinning the molex to pci-e adapters that come with GPUs, so the cost is in wire and crimp terminals. Pretty cheap, in other words. Just wish I knew a faster way to do it
