Those are fun because they're a super awkward shape, and because mains input and DC output are tightly packed together on one end.
Ya, I have a few though from a chassis so I just soldered up a C19 on the AC side and 10ga wire to the dc output. Have a raspberry pi running AWS IoT code to control power on/off remotely. Working on getting the I2C and some other data gathering working now. Would be way easier if there were a decent breakout for them though
