I'm digging this thread up from the grave because there are still some interesting things to do here with this case design and the types of power supplies I tested. Still itching for a brickless console-style case, though my approach will be more to support 12V units like the G-Unique cases.
I no longer have a 12V Pico style plug-in unit but I still have the brick, and I know from my
previous testing shown here that it does work with no permanent modifications.
Considering the size of the power supply I'm using, a case for this type of PSU will have to be 70mm in thickness. That is 6mm more than the NFC S4 Mini and 4mm more than the Sentry, but also means you could use CPU coolers as tall as the Cyrorig C7. I'll see what else I can come up with in the near future.
