EK Announces the EK-Quantum InWin 977EK PC Case

EK, the leading name in custom loop liquid cooling, is proudly announcing the launch of the latest water-cooling-focused PC case made in collaboration with InWin, the renowned case manufacturer. The new EK-Quantum InWin 977EK was engineered from scratch with water cooling and ease of use in mind. It’s a premium quality PC case that can accommodate two 420mm radiators, has dedicated mounts for pumps, reservoirs, and combo units, and offers the ultimate user-friendly experience for custom loop liquid cooling enthusiasts.

EK-QUANTUM INWIN 977EK
Crafted from a single, robust piece of 4mm-thick, high-quality brushed aluminum, the outer shell of this PC case proudly embodies the iconic InWin aesthetic. Meticulously bent by skilled artisans using hand-operated techniques, it showcases their dedication to craftsmanship.

Ease of Use
Both the top and the bottom part of the case utilize removable dust filters and radiator mounts that slide out the back of the case by loosening only four screws from the back panel. This greatly simplifies the maintenance and installation of the radiators with fans.

The robust motherboard tray can slide out at the back of the case, simplifying the PC building process. This allows you to install the motherboard, CPU water block, and complete GPU and water block assembly hassle-free.

The power supply mount also slides out of the case, at the same time acting as a pump, reservoir, or combo unit mount. It supports tubular-style combo units like the EK-Quantum Kinetic TBE 300 and flat-style units such as the EK-Quantum Kinetic FLT 240. A dedicated cutout for a rear-mounted pump lets you install a flat-style combo unit directly without using standoffs. In this case, the maximum PSU length allowed is 215mm while considering the space cables and ensuring they don’t collide with the pump.

Rail-Fitted Radiator Mounts
The mounting slots on the radiator mounting frames are centered so you can swap between 120 and 140mm type radiators, and the ports will still be positioned the same.

The maximum radiator length is 360 or 420mm, even supporting longer X-Flow variants. A Slim series Surface radiator will sit flush with the mounting frame of the case, and a P series 44mm thick radiator combined with 25mm fans will fit with no issues. To be more specific, the top side has a clearance of 75mm until hitting the motherboard tray, while the bottom has 89mm. This means there is room for a 58mm thick X series Surface radiator and 29mm fans in the bottom. Still, EK recommends the maximum thickness of radiators to be 45mm, which translates to a P series 420mm radiator as the recommended maximum.

Invertible Design
This case’s ability to slide components in and out is not just a mere convenience during the building process but also allows users to transform it into a reverse ATX setup. By simply rotating the power supply mount and the motherboard tray and sliding them back to the opposite side of the case, you get a reverse ATX setup in a matter of seconds. This means that if your preferred position of this stunning PC case is on the left side of the desk, it can still fully showcase the internals.

All this is possible thanks to the sturdy aluminum extrusions in the bottom and the top of the case. These act as rails for all the sliding components and significantly improve the structural rigidity of the case.

Hardware Compatibility
As previously mentioned, there is no particular PSU size constraint unless the power supply mount is simultaneously used as a combo unit mount with a rear-facing pump. The dedicated space for combo unit installation offers many mounting holes, allowing maximum flexibility when moving the unit around. It can also fit two FLT 120 units for a dual loop and even the upcoming 140 and 280mm Kinetic combo units.

RGB-Lit Capacitive On/Off Button
The capacitive Power-On button in the shape of the EK logo is located at the front. It is RGB-lit, and its inside cable guide rotates to account for potential inverted mounting.

Rubberized Feet
The 977EK features two wide ridges along its base acting as feet, additionally raising it and providing stable support when placed on a surface. This gives ample airflow to the bottom radiator and adds to the striking visual appeal of the case. The attached rubber strips take care of the vibration dampening.

Legacy Drive Support
The removable hard drive mount located on the back side of the motherboard tray allows the installation of 2.5″ and 3.5″ drives. The limit is the actual height/thickness of the devices since it supports up to 26mm. This should not be an issue in the era where SSD drives prevail, as these solutions are significantly slimmer.

Ample Cable Organization Space
The frustration of encountering insufficient cable space that leads to difficulty closing side panels is a challenge familiar to many. To address common frustrations with cable management, the EK-Quantum InWin 977EK offers a generous 32mm space for effortless cable organization. To help mitigate the cable management issue, the backside of the motherboard tray is equipped with a great number of slotted holes that can be used as tie-down points with either zip ties or the included reusable touch fasteners.
