"If you are in the market for a mini ITX case and want something you can grow into, the Colossus is a good choice. Its modular design allows plenty of configurability and can accommodate even the largest of video cards. If water is your thing, you don’t need to break out your hole saw/Dremel… BitFenix has you covered. This isn’t the cheapest mini ITX case on the market, when you grab one you can easily see why. Bottom line… would I buy one? Yes."
