I used to buy cases based on the looks but I've finally learnt to not do that! Problem is that you see photographs taken by professional photographers in perfect lighting conditions and then probably touched up in Photoshop too. Colour, finish etc never looks as good unless you also have perfect natural lighting where you're using it. If you're determined to choose one based on looks, at least look at photos people have taken of the case sitting on their desk. Then you'll be seeing it in a more realistic light. As for cost, Coolermaster Storm Enforcer is very highly reviewed for build quality, cooling/noise, ease of installation etc and can be had as low as £60, maybe lower if you find a deal.
