Today we wrap up a series of reviews on products that were used to build our new Sandy Bridge-E test system. If you aren’t familiar with the series, the idea to upgrade my 2nd generation Core i5 test system started during our trip to CES earlier this year where we got to check out some really slick components from multiple companies for 2012. We’ve covered pretty much every part in the system thus far save for today’s product, the colossus Cooler Master Cosmos II.

Unless you’ve been living under a rock for the past several months, you’ve no doubt seen this chassis online or perhaps even at your local hardware retailer or LAN party (although I pity the person responsible for lugging this heavyweight anywhere outside of their house). Cooler Master showcased what they call the Ultra Tower at CES and it goes without saying that it was the most impressive computer case I saw during my week in Las Vegas. We've been anxious to get this chassis on the test bench to see if it lives up to the hype.

Before we dive in, let's have a look at the specifications list borrowed from Cooler Master's website.

With support for up to 13 hard drives and a total weight of nearly 50 pounds without any hardware installed, this is probably the largest case I have ever worked with. That's saying a lot since I've been reviewing hardware for over 10 years now. Anyway, let's move ahead and see what all the fuss is about.
