Case arrived this afternoon and the good news is the CPU cooler fits! Case is a Streacom FC7 Evo and was bought from ebay for £39 and you might notice, it doesn't have any front usb ports. I prefer the cleaner look, but as it's going to be in a cupboard it's no big deal. Case is nice and it went together in no time.
Fitted an Arctic Cooling F9 CO 92mm PWM fan as an exhaust to the side of the case. There's a bracket for an 80mm fan inside which uses 2 screws to hold the fan in - I just used one screw and the case lid pressing down on top of the fan to hold it secure.
Set it up as silent in the bios and it's dropped my idle temps by around 10˚C and the Prime95 Blend test by around 8˚C. Up close the fan motor has a faint ticking noise when running so slow, but I can't hear it with the door closed on my cabinet. I hear a very quiet whoosh when it's stress testing in a silent room once the fans have ramped up a bit. Not very scientific I know, but it works for me......
