After adding a second Mac mini to my homelab, I wanted an enclosure that would keep them secure because the last thing I need is for one of them to fall off a shelf.

I decided to go for the MacRack mini from Sonnet. It has plenty of cooling for the new 2018 Mac minis, and it's a sturdy enclosure. Here are the specs for each mini:

2012 mini running pfSense: 4 core 2.6Ghz i7-3720QM 16GB RAM 256GB and 1TB SSDs

2018 mini running ESXi: 6 core 3.2Ghz i7-8700B 32GB RAM iSCSI storage on Synology
