That seems reasonable, I don't buy NAS for datacenters (just run a modest 80tb one for my home lab) but equivalent rackmount 16-bay ones from other vendors would be more expensive (maybe $5k-6k?) and with less polish.
Yeah, I'd certainly take it over this:

I paid ~$4900 in October 2021 for a TrueNAS MiniXL+ with 8x14TB, 2x480G SSD (L2ARC/ZIL) and 64GB RAM, 2x10Gbps, with 3 year support direct from IxSystems. The CPU is an 8 core Intel(R) Atom(TM) CPU C3758 @ 2.20GHzStill going strong. I had drive failure and they replaced it. I had a fan failure and they replaced the fans. The price of the UI kit in 2026 seems to be reasonable.

I laughed.
