I still haven't milled the blocks, but everything has arrived now, other than a few odds and ends. I am now mostly done with the control panel- only have a few holes to put in for the power, RTD, mounting hardware, ventilation fan and the switchcraft power connectors that I will use to connect the controller to the cooling units. Still have to get those things milled, however. I will include a few pictures.
The whole thing is 8x4x14".
