I think as a turn-key solution, the prebuilt enclosures are fine. I have a two-bay Synology that works well. If you’ve already got components though, DIY is probably going to give you a lot more granular control. I’m planning on building out a home server rack including a TrueNAS VM or something similar.
That’s awesome to hear. I’m looking to set up some self-hosted stuff, and I see a lot of recommendations for Tailscale for the VPN element.
