And if you just want a NAS? It is really hard to go wrong with a 4 bay NAS from one of the reputable vendors (which may just be ugreen at this point?) as those tend to still come out cheaper than building it yourself and 4 disks means you can either play with fire with RAID5 or not be stupid and do RAID1.
Actually ASUS started to sell N100 motherboards with the CPU soldered on for $120
That plus a jonsbo N2 or N3, a few extra pieces, and its a few hundred dollars cheaper than the Ugreen options. Sure it will probably run Truenas instead of Ugreens custom truenas or whatever its built on, but that extra $300 is another 24TB hard drive or a HexOS lifetime subscription.
There’s also always the classic buy an old mid sized tower for $100 and slap two massive hard drives in it


There’s a few options now, but you can get Intel N100 ITX boards Like this one from ASUS with a soldered on N100 CPU for the cost of a normal motherboard.
If its just a NAS, and I do recommend having a separate Just a NAS, that CPU fucks hard.
