Wall mountable case

[Rusty2012]

I'm in the middle of renovating my house and my man cave is about to become a nursery
I'm now having to relocate to the lounge. As the area I have is much smaller I'm looking for a gaming case that can be wall mountable. This is going to be a complete new build so open to suggestions I would like to water cool so things dont get too noisey and I only plan on running with 1 gpu.
The only cases I have seen so far that fit the bill are the lian li o series and the thermaltake core p5.
I'm swaying towards the lian li pc-07s but I can't find prices anywhere. I'm not in a great rush either probably looking to start the build October or November as I plan on giving my current rig to my nephew before Christmas.

Any ideas or advice is greatly appreciated!

Thanks everyone for your advice. The reason I liked the lian li is because of the design. Yes there's limited water cooling potential but I have done a quick search and it has been done. I guess it just needs more planning due to being so narrow.
I want my system to be as quiet as possible as it's in the lounge so water cooling is a priority.
As for the thermaltake P3 I dont like the way the gpu overlaps the fans for the rad in the pictures I've seen.
However taking price into account the O7 is just ridiculously overpriced and as much as I like it its about £100 more than I'd be willing to pay.
I might have a look at the O6 and see if watercooling is viable if not I'll have a bit of a dilemma in a case I'm not keen on or spending more than I'd like
