The 12A supply was very cheap to let it pass. However, it doesn't seem to be too big. Just slightly larger than the 3A supply. Same open frame construction.
Specs do not call for mandatory forced air cooling, so no fan is required. The most obvious differences being the slightly larger PS, filter caps and four TO-3 regulators instead of a single one in the Power One unit. But I understand your concerns about heat and EMI radiation. I'll probably just enclose in a dedicated Context Engineering box, just like the other one. BTW, the MTBF of the unit is in excess of 200,000 hours, BTW.
