TechREACTION Review: Bitfenix Merc Alpha
 

Getting a quality gaming chassis doesn't necessarily mean spending a small fortune. BitFenix took that to heart when making Merc, which comes in two versions, the Merc Alpha and Merc Beta. The Merc Alpha will give you the option of going with additional fan locations, while choosing the Merc Beta gives a more streamlined look. The Merc has plenty expansion possibilities, which means your Merc can grow with the rest of your system, while friendly DIY features make system installation headache-free.
