I also have a Synology and it kind of blows me away how much stuff is just... available. And whatever isn't available you can install via Docker pretty easily.

I also have a Synology and it kind of blows me away how much stuff is just... available. And whatever isn't available you can install via Docker pretty easily. One thing to watch out for is upgradability. My system has 4 GB of RAM, which is Not A Lot. There's an easily-accessible SODIMM slot that I can throw an 8 GB stick into, and an almost-completely-inaccessible SODIMM slot with the original 4 GB. If you're going to have slow disks you'll need lots of disk cache, and maxing out mine is looking to be a full afternoon project and not a quick in-and-out.
