I dusted off my RPI4 and started tinkering with self-hosting things and it’s sparked a fire. Suddenly I have 7 docker containers running and I need more RAM, more space and I want something reliable with room to grow. I like small form factors but it doesn’t need to be RPI small. Any recs for your favorite hardware under $500?
I have some (refurbished) HP mini PCs that are pretty decent, you can probably find similar things well within that range. You could also consider an off-lease/used server in that price range, but will have to do some hunting to find something you like. Also, servers can be a bit loud and power hungry (the efficiency of the compute is lower than e.g. a mini PC or a Pi, but it will have way more compute. Servers with something like dual hex core CPUs and 64+ GB of RAM are not uncommon).
I run both mini PCs and server hardware, using the server hardware mainly for storage or services that need quite high availability (auth, reverse proxy, password vault) and the mini PCs for most everything else (minecraft servers, wiki, jellyfin, etc)
HP EliteDesk 800 G3 go for about 110€ on eBay in my area so they should have similar pricing in the US. Bought three of them and upgraded each one to 32GB of RAM and 1TB of NVME storage. They’re near silent and draw very little power which is perfect for me. I’ve set them up as a Proxmox cluster to host a bunch of VMs for messing around. I wouldn’t recommend them for applications that do video encoding though. Plex for example can bring one of these machines to its knees when you’re dealing with very large 4K Blu-ray rips like I am. In that case I usually just run Plex on my desktop when I need to.
