I wouldn't recommend a HC4 anymore, if you want to have a SBC system, there's faster options for less money available now. Have lost track a bit, but something with a RK3588 would be quite a bit faster, or maybe the Pi 5. Or go the refurbished SFF PC route.
Using an ODroid HC4 I think it's called? It looks like a toaster. nostr:nprofile1qyghwumn8ghj7mn0wd68ytnhd9hx2tcpz4mhxue69uhhyetvv9ujuerpd46hxtnfduhszrnhwden5te0dehhxtnvdakz7qpqhklphk7fkfdgmzwclkhshcdqmnvr0wkfdy04j7yjjqa9lhvxuflsmmg6ss had a good guide on how to get Umbrel running on it. Been solid but can't run too much on it, only 4gig ram

I agree. The HC4 was a decent option when no one could get their hands on a Pi 4. I'm already looking to upgrade over a year later
