Being a great fan of [Stéphane Graber's videos](https://www.youtube.com/@LXD), where he once showcased his 3 servers cluster bought on ebay for "250-300$" each, I decided to take that that as my price base.

So, it's worth mentioning that server manufacturers are apparently not the best in class when it comes to open standards, interoperability, support and maintaining legacy hardware. HPE, as you'll read [Part 2: Install the server](later) is even pretty bad on that front. Unsupported hardware, unmaintained software.
I read Go HPE with HPE For instance, I read that HPE is only supporting their own brand of hard disks (not the cheapest one obviously). Some hardware may work fine, but some disks might have the effect of having the fans running full speed continuously.
