Around the back end of October, last year, we reviewed the original BitFenix Colossus cases.  We were impressed with both the black and the white versions, however, the cases we reviewed were pre retail samples so I was reluctant to use our normal award on something that wasn't yet a retail product.  Today, we are going to take a look at a retail sample of the Colossus, the Venom.  The Venom is a black Colossus that comes with green and red LED lighting, rather than the blue and red of the original models.As with all the Colossus retail variants, Bitfenix have implemented a number of updates from the pre-retail samples, taking on board feedback from reviewers. As we've already done an in depth review of the Colossus, this will be a shorter review, focusing on the changes between the original samples and the retail implementation.  I'll also be testing the Venom using an i7 X58 build to add to the experience we had last time with the AMD 1090T build.  So without further ado, let's get on with it...
