+ a €49 setup fee.

I've never really understood Hetzner's offering, I can get paying €2.4 for a quick one off or a once a month build but I don't get how €98 + €49 per additional month is better than buying a Mac Mini on a payment plan.

If in a business context the alternative is "the CI macs, that sit in some corner of some office under a desk and hopefully don't get unplugged", maybe with a side of "and IT hates unapproved servers and also won't put our macs in their DC", I can see it making some sense.

IMHO unplugged once or twice a month, or GitHub Actions being unavailable it's pretty much the same thing.
