If anyone has any complete rigs (ie, ready to run with hard drive, GPUs, power etc, monitor of course not necessary to be included) from the GPU mining days then let me know as I am in need of some GPU computing power for other purposes (rendering, statistical calculations etc). Ideally should have at least 6Gb of GPU but open to suggestion. Will accept even very large and powerful rigs as a lot of power is needed. If you are experienced in building rigs then get in touch too and we'll discuss requirements and arrange a price.
PM me with any offers and I can discuss it via Skype if you'd prefer too. Payment in bitcoin.
Please contact me - I work with Stricture Group and we sell professional GPU compute servers for OpenCL loads (mostly focused on password cracking, but we've sold hardware for other purposes as well).
Our hardware isn't cheap, but unlike a lot of mining rigs, ours actually works for other things. Many of the mining rigs use PCI extenders and function tolerably with the very light GPU traffic of mining (there's very little communication over the PCI bus), but will not remain reliable with any other, more data-intense workloads. It will work for a few days, then drop GPUs, or hard lock, or do other things that make long running jobs fail.
I'd be happy to discuss your workload and see what we can get set up for you!
