I’ve had good experience with the Minisforum MS-01, while it’s more than your $200 mentioned, it’s been worth every penny. Plenty of power for most homelabs and lots of nice features for future proofing (10gb, Ethernet, plenty of storage options, small but still usable pcie expansion slot) in a small form factor.

I’ve pretty much retired all my RPis at this point and my old Synology NAS is now just storage only with the MS-01 doing all the actual work.

Really don’t have a reason to migrate away from it for many years unless it died. Even then, you can create a promox cluster with them trivially to provide some redundancy.
