"To an extent, your computer case defines your computer. If you get a 1U rackmount chassis, chances are that you are building a server. If you are using a mATX small form factor case, the aim is portability. A general mid-tower or full-tower case is used for mainstream and performance computing. As computers are now an integral part of many living rooms, the trend of stylish HTPC cases are becoming an important product line of many case manufacturers. NZXT, established in 2004, is starting their quest to become an important player in this market. When they contacted me roughly a month ago in regards to reviewing their products, what really interested me is their NZXT Duet -- a HTPC case that is designed to accommodate both vertical and horizontal placement. Besides external appearance, how well is this case engineered, and how does it perform? Although we haven't reviewed a computer case for quite a while now, it's time for us to get back to it -- and let's examine NZXT's Duet today."
