These are great units; while I wouldn't grab any without all the needed parts, these are still at an awesome deal for what they are.
A little bit of 3D printing or CNC can get you a nice backplate as well if you wish to transplant into a reguler (maybe a Supermicro) chassis.

Quick break from the above WIP post:
While messing about with updating FRU info, I believe I've found the correct raw IPMI values to address fans on the SD1Q-1ULH;

Hey all; I've been eyeing these units as I have a Supermicro X10SDV-TLN4F running the same Xeon D-1541 rock solid;
FedEx as usual loves destroying things so out of the two purchased was able to get one usable frame (already talking to seller to have the other replaced).
I was still able to go...
