The New Fractal Design Define 7 loses the R but gains even more ease of use for system builders. No matter your taste, this case is versatile enough to cover your needs. Want a rainbow puke machine? Get the Define 7 with a tempered glass side panel and load it up with enough RGB to satisfy your urges. If RGB isn’t your thing, omit the rainbow barf, and you’ve got a case that has a clean, understated look that will fit in anywhere.

If you’re someone who prefers silence over extreme airflow. The Define 7 has your back with its sound dampening panels and included optional solid top panel, the Define 7 can be as quiet as you like it to be.

Alternatively, you can swap out the top panel for an airflow version and put more fans or radiators at the top of the case.

Cable Management

Cable management in the Define 7 is excellent. It’s something Fractal has been refining over the years, and if you are a system builder like me, you will find this case a dream to build in.

Notice the cable channels in the rear of the case for things like your 24 pin connector and CPU power connector in the image below. Also seen in the image below are the rubber grommets and their placement. You can also see the fan hub under the top lip near the center of the case.

Cooling in the Define 7 is overall decent and modular. You can put a focus on more airflow or choose to focus on silence. During my testing of the default layout, my CPU temperatures were on average about 57C over ambient with ambient temperatures being 21C. That is with AIDA64 running for 30 minutes on my test system.

Cleaning the Fractal Design Define 7 will be simple enough with its included fine mesh nylon dust filters. There are x2 dust filters in the front of the case with easy access. There is one dust filter at the top of the case and a full-length bottom dust filter that pulls out from the front of the case. I don’t have to tell you how nice it is that the bottom dust filter slides in and out from the front of the case as appose to a rear sliding filter.

Front I/O

The front I/O has a clean and minimalist look and feel while still delivering plenty of ports. Included in the front I/O are two USB 2.0 ports, two USB 3.0 ports, one USB 3.1 Gen 2 Type-C port, a mic, and a headphone jack, a reset button, and a power button.

Water Cooling

Now, of course, with a case like this, there will be plenty of people who choose this case for their next water cooling project. With good reason, this is a case built with water cooling enthusiasts in mind.

The case has room for up to a 420mm radiator, an included multi-use bracket that can you can use to mount your pump, and the top of the case has a cut out for a fill port.

The top of the case has support for a radiator of up to 420mm in length. Meanwhile, the front has room for a radiator up to 360mm. The bottom of the case also has radiator support, supporting radiators up to 2800mm in length.

Final Thoughts

The Define 7 is a continued refinement of previous generations of the Define series. It commands a premium price that delivers a premium build quality. The plastic covers on the bottom power supply shroud for example are a nice improvement over previous generations. This refinement makes removing the covers much easier should you wish to put a radiator in the front of the case.

The fan hub is also a welcomed refinement. It’s not only functional but well placed for ease of use.

The Fractal Design Define 7 is a nice case to work in. You should have no problem building your next battle station in this (in my opinion) beautifully designed case.
