OP here, yes I use the hetzner marketplace for used dedicated servers. I have found that using hardware that's 6+ months old actually decreased failure rate. Plus it's cheaper and they waive the setup fee.

The marketplace has some really good deals on it! Thanks for sharing.

Of of the good aspects of Hetzner that they also offer desktop CPUs which are often more powerful than the so-called enterprise CPUs (see https://jan.rychter.com/enblog/cloud-server-cpu-performance-...).

I've gotten servers from Hivelocity in the past, they like(d) to offer servers with the "enterprise" equivalent of these CPUs, I'm not sure if Intel still sells them, but there used to be a "xeon i3" basically, usually 4 core CPUs clocked to the moon, that supported ECC. They were really good!
