the pittsburgh modular structure cases are ok but I know nothing about the quality of their power solutions
-- JimHowell1970

From what I know, they're actually Monorocket designs, and Monorocket was always keen on overspecced Meanwells. Pitt is obviously continuing in that vein. Lots of no-screwing-around design in evidence; for example, check https://pittsburghmodular.com/structure and have a look at the 344...and take note of the THICC bus wiring in use to send DC to the upper distros.

More spendy, to be sure...but they're majorly overbuilt, overspecced on current ratings, and so on. You get what you pay for there.
