I will take 3 of them to test, kind sir Finksy.  I don't know the whole sign thing, so whenever you're ready, just PM me and I will send the payment.

P.S For those that don't know...........these IBM 4KW bundle are also awesome when paired with a small PSU for Ethereum mining.  I'm powering easily 18-24 x RX480 with just 1 x 4KW bundle.  So quiet and efficient!
