They actually had a Mac Mini Server as well for a bit. It made sense because it had a second hard drive instead of an optical drive and came with a Mac OS X server, back when that was a standalone $499 product: https://support.apple.com/kb/SP586

(Not sure what differentiates the later model Mac Mini Servers from the regular Mac Minis, since Mac OS X Server just became a $19 App Store purchase, and optical drives were no longer a thing in Mac Minis)

I have one of the 2009 Mac mini Servers running Ubuntu 22.04 LTS like a champ. It’s still a great machine. Upgrading the HDDs to SSDs was a bit of a chore, but doable.

They discontinued the Mac mini Server line in October 2014, which was still sold with two drives instead of one. Configurable to order with SSDs by that time.
