Fractal Design is probably best know for it's Define series chassis lineup, cases designed for high performance while keeping a low noise level and budget price tag. The current version, the Define R4, was much praised for its customization options, cooling performance, and noise control. However, at the beginning of last year NZXT released their H440 chassis, a case that was called the ?Define R4 Killer,? because of it's enhanced cooling options, quiet operation, and stunning looks. But now Fractal Design have given their answer to the H440, and it's a big one ? the Define R5.
