The Define R4 is the latest in the Define series of silent computer cases. Building on the award-winning foundation of the Define R3, the R4 retains minimalistic yet elegant styling with extraordinary performance, noise reduction features, premium build quality and unparalleled value in this price range while adding a suite of innovative new features.
No longer are you forced to choose between silence and support for liquid cooling, the Define R4 offers both. Top fan positions now allow slim 240 radiators to be mounted internally and select slim radiators can also be mounted in the front fan holder. An integrated fan controller is easily accessible behind the front panel, putting fan control at your fingertips. Cable management and intelligent layout are taken to new levels with the option of mounting up to two 2.5in, SSDs on the reverse side of the motherboard tray, effectively mitigating visible cable clutter. When it comes to cable routing, the Define R4 has it covered. Over one full inch of cable routing space behind the motherboard plate has been achieved by widening the case by just 8mm.
This mid-tower case is a great choice for everything from gaming enthusiast systems to silent home theater and corporate applications. The R4 comes pre-fitted with dense noise absorbing bitumen material on the front, top and side panels. The exclusive ModuVent TM System provides three panels which also have noise-absorbing material; these panels can be removed to expose three air vents for additional fans for high air flow applications. Rubber padding on the case feet, anti-vibration pads for the power supply and HDDs also help reduce noise.
Configuration flexibility is enhanced thanks to two hard drive cages (featuring steel drive trays with black silicone mounting grommets) that support a total of eight 3.5in. HDDs or 2.5in. SSDs. The top five-bay cage is easily rotatable and removable; removing the top cage allows support for graphics cards up to 470mm in length. The bottom three-bay cage is mounted to the chassis by screws instead of rivets, allowing you to easily remove both drive cages for complete flexibility. The spacious sleek black interior can support CPU coolers up to 170mm high. If cooling becomes more of a priority, this system can support up to seven fans with removable, washable filters to provide airflow from five sides of the case. The case also includes cable routing cutouts with improved rubber grommets to ensure greater fit and retention. The bottom of the case has a filter over the power supply and 120/140mm intake fan vent which can be easily removed for cleaning.
Pros: Build quality is fantastic Very sleek looking case; love the minimalist design + the window. Soundproofing foam throughout the case. Enough room to fit 99% of builds. Plenty of space for closed loop CPU water coolers (I believe even the 140mm coolers like the H110 will fit), multiple graphics cards, extra case fans, etc. Plenty of space for tall CPU heatsinks as well (made an NH-D14 look very ordinary!). Nice cable management Built in fan controller, though a bit minimalistic, is nice. It's at least sufficient for the stock fans.
Cons: 2 minor things: 1) I wish the front panel connectors were longer. If they have to reach to the back of the case, you won't be able to hide them easily, as they're only just long enough to reach the bottom rear of the case, and on some motherboards that's where they'll need to go. 2) I didn't really like some of the screws the case came with. I had problems with the motherboard risers being too tight for the motherboard screws that were included. Also not a big fan of the design of the motherboard screws they include. This wasn't a big enough issue to dock an egg for, but I recommend using your own motherboard risers and screws if you already have them laying around.
Overall Review: Really love this case. Easy to build in and looks awesome! Very highly recommended to anyone wanting a mid tower as long as you don't need to put tons of large (360mm) water cooling radiators in it.
