So an update on this one as I haven’t posted in this thread since I tried the last bit of kit.
I’m using an HP 620 G3 as my ROCK host at the moment. This works flawlessly in every way, but then that’s probably because its spec (chipset, ram, drive layout etc) are identical to an official NUC.
The only difference being my I3 is a 7130U rather than a 7100U so it has a tiny little bit more horsepower.
-8GB DDR4 2133
-256gb M.2. PCIe SSD
-2TB External USB
Runs like a charm, doesn’t bat an eyelid when running DSP to two zones and is very compact.
HP actually sell a dedicated add-on module with a CD drive inside it, that bolts to the bottom of the chassis. Meaning you have an all in one mini PC that actually incorporates a CD drive. So I have this connected for ripping via ROCK as well.
All in pretty perfect.
My only criticism, is that in the listening room, with very quiet music, you can just about make out the fan whirring. When I move home, i’ll shove the HP into another room, and use a little HP thin client as an end point (fanless device).
