Ideally one that can use more than one disk so that i can expand it later when i can. Have some minimal experience with Synology since there’s one at work and i have interacted with it a couple times and like the interface, but am not married to any brand as long as it works.
Located in EU if it makes any difference.
Depends which route you wanna take:
Personally I prefer the more DIY approach, as it doesn’t lock me into hardware (e.g can diagnose/replace faulty parts instead of throwing away whole box) or software (synology actually use standard md/btrfs raid so it can be read by any modern linux). Although I was using Synology myself and was very happy about the software
