Master Replicas took over the Eaglemoss stock and they have an XL E for $72.

You could always hop over to https://frame.work and pick up a refurbished Intel mainboard plus an enclosure (or 3D print your own using their plans). You’d just need to get some RAM and a small SSD to run an OS like TrueNAS and you’d be good to go for probably under USD $600.

I got my Framework 13 in February 2022 and I love it. I’ll end up getting the AMD mainboard when it becomes more widely available, then take my old mainboard and RAM, put them in an enclosure, and make that my new NAS. Then my current NAS, which is just a Raspberry Pi, I’ll turn that into a PiHole.
