Within your budget, where all your components fit and with focus on airflow (front mesh panel), take a look at those 4,

E.g making the complete build look like so,

Made few changes as well:
* Removed MX4 thermal paste since NH-D15 already comes with thermal paste. Keep MX4 if you think it's better than the one offered by Noctua. (I too have MX4 thermal paste in use with my Skylake build.)
* Also, replaced low build quality EVGA 600W PSU with good build quality Seasonic Focus+ 650. (All my 3 PCs: Skylake, Haswell and AMD are also powered by Seasonic.) Since PSU is the most important component inside the PC, you do not want to use low quality PSU, if you care about your system.

Did you ever read what OP said? OP specifically stated that he doesn't want cases with solid front panel, which NZXT H500 is. Also, H500 costs £69 and it's out of OP's budget,

Or you just don't care and go around suggesting your preferred components regardless what people want?
 
Aeacus - go have your blood pressure checked! I just SUGGESTED a case to help start Cheese_1's search. It's close to the the requester's price point, has decent air flow, per reviews and is of good build quality, i.e. the things needed for a budget case. Since this is a forum, I expected other's to add to the suggestions and provide options to the requester. There's no need to be a di^%* about it, if you don't like the suggestion.
