Fractal Design Define S Review

Fractal Define S

After reviewing the Corsair Carbide 500r, I had many requests to offer a short review on any of the Fractal Design cases. This brings us to the Define S – Window, and oh boy, I was not disappointed. This mid-size tower offers an innovative design that allows for seamless cable management and space to expand. Having no drive cages allows for 1/4 of usually inaccessible space for use of liquid cooling equipment (pumps, reservoirs, etc..). Even if you aren’t running a liquid-cooled setup, the extra space just makes your build look more like a piece of art than anything else. Where do my drives go then? There are two HD trays elegantly tucked behind the front partition of the motherboard tray as well as two SSD trays directly behind the motherboard tray.

From dust filters on the front and bottom air-intakes to the sound dampening material, it seems the folks at Fractal Design have figure out what I didn’t know I wanted in a case.

In a time where the market is flooded with cases that have more LEDs than functionality, the Define S – Window is a breath of fresh air. They even included straps on the backside of the motherboard tray to help with cable management. If that isn’t enough, packed in the box, along with all the hardware you need to install all of your components, is a bag of zip-ties. It’s the small functionality points of this case that makes you believe that the company is actually trying to design something useful and not churning out glorified shoe-boxes.

My verdict on the Fractal Design Define S

It’s in cases like these (sorry for the pun…) that I wish I could write more than my self-allotted 300 words. So, I will keep it short – this case is close to perfect.
