Looking to get into NAS.

I'm thinking of getting into NAS for the main reason of taking the 260GB of music with me via streaming rather than having it all on my phone.

I'm not really interested in using an old PC for this due to power draw so ideally would like a NAS (single bay is fine) but with enough RAM and the ability to use a SSD so it's quieter.

Does anyone have any recommendations please? Not looking to spend a huge amount, £500 or so.
