Home media server - advice required

[Csne2x]

Hi all, I'm pretty much a novice here so looking for some advice on spec for a home media server. I've listed below what I'm looking to get from it.

Looking for it to store movies, music all that good stuff.
Stream upto 4k onto 3 separate tv's via my network which I have wired with cat 6.
I am looking at running the media side with plex.

There could be the potential for me to want it to act as a pc but firstly a server.

I was thinking about building a fairly powerful pc with good storage but was unsure hence why I've come seeking advice.

I've been looking at bundles or buikding from scratch.

Any help is much appreciated.

Hi thanks for a quick response, what I meant to say was to be able to do 4k as and when it was finalised.

Yes my tv's are 1080, would one of the above mentioned deals be fine with multiple streams at the same time?

To be honest as of yet I don't have a lot of data but I was looking to rip all my dvds so that they are accessible from all rooms in the house.

I was going to go for a 2TB drive, what are my options for backing up the data?

So I think I have decided to go with the Lenovo TS-140 with the cash back it leaves headroom for further expansion. My next questions is what operating system would I better be using. Like I say I probably wont want to do too much with it other than media and such. I'm not all that up to scratch with operating systems but currently run Win 10 on my laptop so I was thinking that.

Is this any good on the Lenovo TS-140?

Thanks in advance for any advice.
