If you're spending 170 euros on coffee then you're either abnormally rich or abnormally bad with money for a Dutchman.

Without the ability to upgrade either storage or RAM, a 256GB SSD with 16GB RAM is quite useless for a home server. Minisforum doesn't offer any options with that little RAM and storage it seems (you can pick between barebones and 1TB models).

The bare minimum spec for the Mac Mini sits at an interesting price point, but if you use it for any more than the bare minimum it'll be pretty restrictive with how memory-hungry macOS has become. No Linux support to speak of also makes for a rather mediocre home server experience.

One interesting part I found out of Apple's European pricing is that after currency conversion and subtracting VAT, the European price is still equivalent to $700, which is $100 more than they charge within the US. Looks like a 1/6th price increase is all you need for consumer rights!
