Any recommendations for a replacement NAS for MinimServer

[simoncn]

There are a few similar models in the current QNAP range:

TVS-h474
TS-473A
TS-453E
TS-464

I suggest you compare the specs on the QNAP website to see which of these is best suited to your needs. You should be able to use your current HDDs in any of these.

As an alternative you could look at the Synology range. Synology typically withdraws software support for older models after a shorter period than QNAP, which could be an issue if you want to keep the NAS for a long time.
