How can I improve the aesthetics of my case?

[Xeron]

Hello,

I've just got a few questions about upgrading my PC build, and also the build in general (cable management etc.). Please note that we're planning on moving, so no 'permanent' solutions (i.e. nailing stuff down, getting a new table etc.).

1. What 'mods' could you recommend to improve the general aesthetics of the case without sacrificing much efficiency, especially in heat reduction? I'm generally going for a white/black theme, which will help me if I ever do decide to get RGB LED's so that it works better on white.
2. What suggestions do you have for getting better cable management both outside and inside the case? I've done my best with the exterior (as you can probably tell, although I know it's not great) but I've pretty much just left the inside to do it's job - most of the cables are just crammed down the back.
3. This is a bit unrelated, but is Kinguin a reliable site? I'm planning on getting a windows pro license from them for £15, which seems a bit too good to be true (please only comment if you actually know anything from then, not just an assumption).
4. My CPU is acting a bit on the slow side - I've contacted amazon and they told me I can get a free replacement for both the motherboard and the CPU within a year (the CPU fan socket was broken on the motherboard without me being aware, and I was seriously taking it to its full potential on it's first day, which may have damaged it) which I'll probably do towards the end of the year to get a spanking new model. OR, if I do decide to SLI the 960's then I can always just get a refund towards the end of the year and purchase the SLI Krait Edition MSI board (it looks sexy white too) as well as upgrade the CPU. What do you think?
5. Anything else you want to say?

I've bought Heroes of the Storm character codes off Kinguin before. Seemed like a legit company to me.
