Update:

Hosting:
The switched PDUs and PSUs are arriving early next week. We have chosen 550watt 80+gold PSUs to give both high efficiency and fine grain control for power cycling boards should the need arise. Each PSU will power between 13 and 15 boards, depending on the final power usage. The PSU will then be connected to our switched PDUs, which gives us the ability to power cycle the PSU remotely. The network infrastructure and configuration is nearing completion, and we will be ready to receive the units once they are assembled.

Hi SB,

maybe you should consider revising your choice of the PSU or plan less boards per PSU.

According to the best practices you shouldn't run a PSU at more than 70%. So a 550W PSU would be most efficient running at 385W. 12 boards running at 32W each would consume 384W and with slight overclocking even 12 boards would push past the 70%.

+1 on the case. Is that 21 boards in there? I wonder what would it look like once you plug in all the cables.

Cheers

24 x K16s. Cabling should be neater than you'd think as the design is based around a central controller and power distribution unit PCB (CCPDU). Two wires will run to each of the "blades" (composed of 3 X K16s) where the wiring will then branch out to individual boards. So only 16 power wires running throughout the chassis.

Data comms are another thing, but the plan is to use an I2C chain terminating in a single USB connected K16, which will in turn be connected to a Beaglebone Black which will act as a controller and cgminer/bfgminer host.

I know I am a bit late on this, but +1 on the case as well. Curious what the pricing would be, but given the PSU(s), cases, cabling, and time/effort involved, this seems like it would be a big win for those of us who bought more than a handful of boards.

Is there any update on if this is going to be offered (or what price it might be offered at)? Didn't see anything on http://liquidsyndesigns.com or further mention in the thread...
