NZXT Beta Mid-Tower
 

When building a PC on a budget, one of the most difficult components to pick out is the chassis. For many, $100 is the sweet-spot, as it usually gives a solid design and great aesthetics. With the help of the Beta, though, NZXT helps prove that even $50 chassis' can handle the task at hand just fine, and after our look, we're impressed.
