I don't get out much, just noticed this thread.

I squeezed 2 Saturns (4 ASIC and 2 controller boards)
plus 2 consumer PSU's
plus 2 water pumps in series
plus a 60mm thick radiator
into one of my Saturn cases.

Slightly overclocked











My HW is a moving target.
Different WB's and other improvements in process.
(gonna lap my ASIC's while they are installed on the PCB's)

YMMV
