Interesting, but somewhat overpriced and half assed.
You can get a used tiny or micro business unit, complete with psp and case for that price. With more bang under the hood than this, and not a raspi-style cables-everywhere spaghetti solution like this.
What would you recommend? Where can one find those businesses units? I looked on ebay but was only able to find normal mini computers, no energy efficient SBC ARM boards.
There are more in detail later articles, also dealing withore modern units, and the prices are from 2020, where lockdown and other factors spiked a big demand.
I'm more into beginner's server units, and I've sourced a Supermicro X10 based 1u server for EUR 75 including shipping on one ebay night.
Patience is the key, and probably best set yourself an upper limit price wise.

You pretty much just look under your feet usually. Globally they get dumped in bulk on ebay, local platforms for p2p sales of used stuff also have them in most of the world. @Cobrachicken
