Anyone know of something equivalent to the HL-8 from 45homelab but more affordable? The price ($700) is obscene for a barebones chassis that is just a backplane w/o cpu/mobo/ram/psu: https://store.45homelab.com/configure/hl8

The Unifi UNAS Pro looks pretty cool (and my entire rack is Unifi) but I want more control over the OS and would prefer to run TrueNAS: https://store.ui.com/us/en/products/unas-pro

I am shopping to replace a DS918+ that has been in service for almost 8 years. Honestly it's been rock solid without a single hiccup - even upgraded the entire pool disk-by-disk a few years back without problems. But I was already losing interest in Synology's OS and after their recent shift to locking down drive options that is the nail in the coffin so I wanna build my own.
