Not sure how interesting this will be to people, since POWER8 is a very niche architecture, but anyway I ran into this:
Tyan Rack 2U Server TN71-BP012 1x IBM POWER8 10-Core CPU 2,926 GHz 2x 750Watt
299€, currently showing 7% off
Seems like a good deal for anyone wanting to get their feet wet with POWER. Doesn't include any HDD trays but the photos show the rear dual HDD tray is still present.

Be advised it only accepts DDR3L-RDIMMs!
