Take An Even Closer Look at Y40.

Start with a deeply harmonic, core design structure, and connect those details across multiple dimensions. Every edge of Y40 is accounted for and adorned with tightly controlled beveling aesthetics.

2-Piece Panoramic Glass construction sets the stage for a completely unobstructed view of your system’s performance. Tinted tempered glass blends seamlessly with black interior to compose individual components into a clean and cohesive visual assembly.

Ginormous Vertical Graphics Support

Y40 delivers upgraded performance, compatibility, and aesthetics that expand on Y60’s exclusive vertical graphics card architecture.

Worried about the next-gen of larger and more power hungry cards?

Y40 supports 4 full slots (95mm) and accounts for additional airflow space between the GPU and glass side panel. An intake fan hidden below the power supply shroud provides fresh air upwards, further improving GPU cooling.

Included: PCIE 4.0 Cable

  • An included PCIE40 4.0 Luxury Riser Cable supports the latest and greatest graphics cards and its canopy is color-matched with your Y40 color choice (just like the Y60).

Stack Your Expansion Cards

Going vertical graphics orientation typically limits users to a single PCI Express card which prevents expansion… but not here with the Y40!

Y40 includes support up to 6 half-height expansion cards behind the primary graphics card.

Capture cards, PCIE SSDs, sound cards and other PCIE expansion cards are compatible as long as they're available in half-height form factor.

Y40 Gets Even Cooler

Y40 inherits a similar airflow design to its older sibling with nearly the same wide range of cooling support

2 Pre-installed Fans


2x120mm fans are pre-installed: one beneath the power supply shroud and one at the rear. Side-mounting a liquid cooler provides an extra set of fans to drive airflow through the case.

Side Mount - Radiator Support

Up to 280mm

Y40’s side mount can fit up to a 280mm radiator with a combined thickness of up to 120mm allowing for large 60mm+ radiators to be used for custom loop builds.

Ceiling Mount - Radiator Support


Y40’s top mount can fit up to a 360mm radiator for a dual radiator set up.

Y40 also brings support for large air coolers over 180mm in height—allowing for almost every CPU air cooler available on the market.

Optimal Airflow Configuration

With experience from Y60’s optimal airflow builds and testing, Y40 naturally gains a very similar airflow layout.

Optimal airflow for *air cooled* GPUs is as follows:

- Side: Intake
- Top: Exhaust
- Rear: Exhaust
- Bottom: Intake

When using a liquid cooled GPU and CPU (via a full custom loop or a combination of GPU hybrid cooler and CPU all-in-one cooler) the direction of side fan airflow has less of an overall thermal impact when compared to airflow for an air-cooled GPU.

A Simplified Building Experience

Cables Managed and Shelved


Y40 features a robust cable management strategy with cable management spaces and tie downs behind the motherboard shelf and within the power supply shroud.


HYTE’s new “cable shelf” design is deployed within the power supply shroud cavity and allows cable management to sit further back in the case and away from vital airflow zones that impact GPU cooling.

Tool-free Accessibility


Accessing your inner Y40 through its side panels can be achieved without tools and thumbscrews.


But if you need to remove the front glass for assembly, it’s secured with screws to the top, bottom, and side of the case. Just make sure to replace them when you are done!


Complete your desktop’s “Instagram aesthetic” with your choice of Y40’s fresh colorways: white, black, and red. Flex on ‘em afterwards with #HYTEUPSetup.

How it Compares to the Y60

Y40 features superior air-cooled GPU thermal performance when compared to the Y60 due to its larger clearance between the GPU fans and side glass.

Thermal tests were performed using a 280mm side intake radiator with fans set to 1000 rpm and 3x 120mm top exhaust fans also set to 1000 rpm across all test benches.

With Y60 side glass installed some cards experienced thermal throttling. Results were excluded
