The fan placement is a little weird. Axial fan(?) from closed panel to open area at the ATX connections? Air channel to the closed AC wire side?

If you look at the photos, there are arrows on the fan indicating airflow. It pulls air from the connectors towards the opposite end with the power input. The AC wire side has slots now.

Also, I agree the 200mm length is limiting. It no longer fits vertically in many cases....

Quite a weird shape... Might as well make it Flex-ATX at this point.

I have a current and an upcoming (hopefully) build with Supermicro 800W PSU (PWS-804P-1R). This PSU is 54.5 x 220 x 40.25 mm. I have trimmed it a little bit, so it's very close to 200mm. The new HDPLEX is 200 * 55 * 40, almost identical.

While not being suited for lots of existing cases, it opens the possibility for interesting custom layouts.

It looks like a fan with an engine jet noise!
Looking forward seeing your build which probably comes with a fan mod!

Hdplex 250w gan have sold out again, hopefully not permanently...

I wonder what kind of Stealth changes will be on the next batch?
