£300 budget

Im looking for my first surround sound system to go with my 42inch tv.

I currently am pulling all my media from my home network using xbmc on my raspberry pi.

Looking at whats out there £300 doesn't sound like much so im just looking for a bit of advice for someone who is completely new to it all.

Ideally I want 5.1 with a smart blu ray player that can assess my home network and pull media over smb and retire my buggy raspberry pi.

If you suggest a speaker setup without bluray I will consider that too.

Here is what I currently like the look of.

Thanks for helping a newbie out.
