If you buy this [0] Startech 25U open server rack (unsure about other sizes), there is a non-zero chance you’ll receive a pallet of them – 9 in total – for the price of one. It’s a running joke in r/homelab. It happened to me, and then I found out it happened to a lot of people.

Also, for this reason, it’s somewhat common to see them for sale at a steep discount in r/homelabsales. Only makes sense if you’re within driving distance, but hey – cheap rack.
