Thanks in advance everyone, it's been decades since I was remotely up to speed on computer hardware and I'd really appreciate your advice and input on the below scenario.
In years past I would give a USB or portable hard drive to my Dad with media on it for him to watch in his room since he went into care which was working really well, however, now a lot of those files have moved to other file types which aren't compatible with his tv. My first thought was to buy him a new tv and then go back to using a USB drive which we only do once or twice a month when I'm able to visit.
Instead, I'm looking at setting up a small PC or laptop there so that I can manage his files remotely and then he can stream them using PLEX to his TV (he can use Netflix, so I think he'd be ok using Plex). Space is an issue, but I have seen these new mini-computer NUC's around, and thinking that I could set it up and connect it, then unplug the peripherals so it's just the box left there that I can them remote access if required.
Are these little things powerful enough to do that? There seems to be a huge range in price and I'm really looking for something that I can just plug in and it will work without adding extra hardware. If they do work, what might you suggest on the market now that would be reliable and good value?
Yes. I used to run Plex from an old NUC I had here. I have since moved over to a NAS that supports Plex, but they can be a little more expensive than a NUC.
I used a small M2 SSD drive to run all the OS and server from and a 2.5" drive to store all the media on. It ran on 4gb RAM and an i3 processor.
I would look at installed Linux over Windows to run your Plex server from. Once it is up and running, you can basically run it as as headless server and do all the config from a web browser.
