Suggest a wireless home cinema system for sub £400?

[darknite]

Ok here is what I am looking for. But might be dreaming here. Ideally 5.1 setup, wireless rear speakers or fully wireless. Works with a Plex Server (reason I list that is my current 2.1 system now turns itself off when accessing the last few versions of plex......) Ideally sub £400.

Am I dreaming? Or someone know of a kit?

Generally always had LG kit. I like the menu's. But in my local shop's all I can find is a £699 kit

Wireless rear speakers would be fine. All front kit can be wired. But the wife redecorated the living room about 6 weeks ago and I don't fancy moving everything around to try and pull the carpet up to run speaker wire.

I saw the LG LHB745 reduced which I thought would do the job nicely. If I was going to run cable.
