How to Guide                                                    

Recently, dual-glass case designs have become increasingly popular. These cases, also called "ocean view" cases, earned their nickname due to their design. The dual-glass panels provide poor ventilation compared to traditional cases, requiring more fans to maintain proper cooling. The sound of the fans resembles the soothing hum of ocean breezes, inspiring the term "ocean view."

While both dual- or triple-glass cases are referred to as ocean view, there’s a clear distinction between ocean view and fish tank cases. Here's how to differentiate them:

The power supply is relocated behind the motherboard tray.

The bottom area is reserved for additional fans, maximizing internal space.

Retain the traditional design, keeping the power supply mounted at the bottom.

This results in a more compact case design compared to ocean view cases.

For aesthetic purposes, I/O ports are typically located on the top panel or hidden at the rear of the front panel.

Since these cases retain the power supply compartment, the I/O panel is placed at the bottom of the front panel for easier access.

Perfect for showcasing internal hardware components and lighting effects, making the build look sleek and captivating.

Particularly ideal for gamers and users who prioritize visual appeal in their setups.

The dual-glass panels allow users to easily inspect internal components, including fan operation, lighting effects, and dust buildup.

Problems can be quickly identified and resolved.

Ocean view cases provide a creative platform for DIY enthusiasts.

From custom water cooling loops to unique component layouts, they allow users to express their style and technical skills.

Both ocean view and fish tank cases emphasize design and aesthetics, offering unique ways to display internal components. The choice ultimately comes down to personal preferences and the desired style. There’s no definitive "better" option—just select the one that best suits your taste and needs.

I was fortunate enough to be invited by darkFlash Taiwan to experience the debut of the back-insertion “sea-view” PC case. The first time I saw this case was at the 2024 Computex booth, where I learned that it features a back-insertion design, three large glass panels for maximum transparency, and an expansive layout—quite unique! When I received the invitation, I also had a set of ROG BTF components on hand, so I took up the challenge. While setting up the system, I hesitated a bit regarding cooling solutions. Almost all water cooling systems on the market still have tubing, and I felt that to achieve the perfect back-insertion aesthetic, something was still missing. Then I remembered that Bitspower, a leading local and international water cooling brand, had recently launched a back-insertion cooling head. After my excellent experience with their CR360 water cooler, I reached out to them, and they were kind enough to provide products for the build. So, let’s dive into this build experience!

The case packaging prominently displays the DY470 logo and design elements, with a very spacious box. The packaging is 

sturdy, justifying the size of the box, and you’ll find the accessory box embedded inside the packaging.

The front cover features a sharp design with three intersecting glass panels that provide a sleek, premium feel. When the lights are off, the edges are defined, adding to its premium look. The top part of the case is made of transparent glass, which gives a more open visual feel when the system is powered on, offering excellent transparency.

The glass panels are secured with screws and feature a quick-release structure, making assembly and disassembly very intuitive.

The rear section reveals that the power supply is mounted vertically, and the fan mounts are designed specifically for 120mm fans.

The accessory box follows darkFlash's signature style, including the traditional glass cleaning cloth and standard screws. Additionally, the instruction manual is included, which is particularly useful since the three glass panels may require some extra attention during assembly. The steps for removing and installing the glass panels are more intricate, and the manual can be referenced to help guide you through the process.

I never imagined that a computer with this kind of gaming "lazy" modeling would actually exist in real life. In recent years, this intriguing build concept has finally come to life, and I was amazed by how visually seamless and comfortable the experience is. I deeply respect the developers and designers behind this innovation. It’s an honor to add such a memorable unboxing to my assembly journey.
