I would offer $9300 for the lot if your interested.  I live in Olathe, so we can pick up the units, but would you potentially be available to help set them up if we make a deal, we could include an extra charge for the assistance with smOS and cabling set up?  I have not worked with multiple PSU's per rig before, so I want to make sure there won't be any issues and we can get setup and running with no problems.
