Welcome to OCN and the HAF XB Club chaps.@wtd03:1. Members here are usually taking a dremel to the top of the case and removing the hump, then some straightforward perspex with some mounting holes drilled, maybe some U Channel to clean it up.2. Any website selling PC accessories, hell, even amazon or ebay wont take much searching to find what you want.@Delta42:@vaporizer has stacked two XBs. See below. Drop him a PM maybe to discuss what hes done to make it possible.
