With the PSU and a micro SD its about 90 EUR from The Pi Hut. A case isn't necessary but can be got for a tenner.

Got a link? The starter set with 32GB SD card and 8GB RAM is £112… so you still have to get an SSD and SATA hat, or the hat this post is about. Then you’re at atleast £125, and your performance will be much lower than the mentioned PC.
