Cool! I just got an Orange Pi 5 Plus, 16GB RAM**, but haven’t set it up yet so can’t give any recommendations. On paper though it looks great — significantly beefier than a RPi 4 (my current server), and supports M.2 NVME as well. Might be worth looking into for your use too, but the emphasis here is kinda on computing with a very low power budget, so I’m sure you could get more horsepower with e.g. an x64 NUC or similar.

Here’s a review, and note that this is without extra heatsink so it was probably thermally throttling (as was the RPi?): www.phoronix.com/review/orange-pi-5

**I first ordered the 32GB version but it got seized for counterfeit postage, and then some shenanigans ensued. If buying from Amazon I would suggest only buying units in stock and shipped from Amazon. May only apply to US though…
