I used to be real into paintballing (a goodly proportion of my 21 some odd years have gone by since I gave that up) and I remembered a howto guide for anodizing barrels on this one website. Lo and behold, said website and guide still exist. I initially thought "watercooling", but I guess there are enough aluminum parts in cases that this could be a "general" topic. I mean, hell, we all know that you'd get far better overclocks in a lian-li anodized black and red, right?
Although now that I think about it, one of those "splatter" designs you see on paintguns could make for a pretty unique case.
