Hardware wise I’d go AIO. A mini and a pair of mirrored USB drives is my setup. I have an off-site backup running: another mini + USB. Finally, I have an inherited laptop as a redundant network box/local backup/immich compute. I have 5 households on my network, and aside from immich spiking in resources (hence the laptop), I have overhead to spare.

An n100 mini (or n150, n200, whatever) is cheap enough and powerful enough for you to jump in, decide if you want to spend more later. They’re small, quiet, reasonable Value for Money, easy Wife Acceptance Factor, and can age into a bunch of devices if you decided self hosting isn’t for you. I’d make a retro console out of any spare mini.

This way, when spending £x00s on a server, you’ll have some idea on what you actually need/want. The n100 can the age into a firewall/network box/local back up/etc if/when you upgrade.

All that said. An AIO storage-compute box is where I’m headed. I now know I need a dedicated graphics card for the immich demand. I now know I want a graphics card for generative AI hobby stuff. I know how much storage I need for everyone’s photos, and favorite entertainment, permanent stuff. I know how much storage I need for stuff being churned, temporary stuff. I now know I don’t care about high availability/clusters. I now know… Finally, the ‘Wife’ has grown used to having a server in the house: it’s a thing I have, and do, which she benefits from. So, a bigger, more expensive, and probably louder box, is an easier sell.
