The best part of having a homelab/home server is the reproducible dopamine hits. First you’ll get some dopamine just getting the thing up and running, but then each service I decide to tackle and implement gives me a whole new hit of dopamine. Most services you can get up in a day or two of tinkering/learning even as a system noob like me. On top of that, if you don’t manage to get it working, it’s pretty easy to scrap the attempt and try something easier.
Then you also get dopamine hits whenever something breaks and you manage to fix it. 10/10 would recommend.
Other than ZFS as someone mentioned already, they also offer dual drive parity now. IMO it’s a good balance to also allow a very flexible and easily expandable array.
