Performancewise this looks similar to https://gist.github.com/SvenKortekaas/60387b0428b1592e5c9ec0... , where the aluminum-case and baseboard were available for about 11USD for a time. (ex. shipping, OFC)

The fitting SBC was about the same price, the most expensive part was the high-efficiencý (GAN) wall-wart, and 2.5" Disk.

I know this, because I ordered this eons ago :-)

Still running somewhere, that thing. 24/7 since then, with some reboots, because updates...

Runs Armbian, if you like to, or anything else if you are willing to mess more.

Seems to be still on sale, according to https://www.friendlyelec.com/index.php?route=product/product...
