I saw this on a Gamers Nexus video and was excited at the possibilities. Technically, it's an SFX-L-sized power supply with right-angle power connectors, and a swappable fan would work very well in SFF builds. If successful, this might be THE go-to PSU option. You can also find it on Streacom's website.

Even better:


I implemented it in 2018 with an ATX PSU.
