Antec DP503 case unpacking/modular graphics card support frame, dual 360mm water cooling installation

A few days ago, I opened the box and shared the DP505 White case owned by Antec. The DP503 I started this time tends to be more low-key in appearance. For low-key gamers who want ARGB lighting to decorate their desktops, the entire cabinet can be installed with up to nine 12cm fans, two 360/280mm water coolers, and the largest E-ATX size motherboard. The hardware expandability of DP503 can be said It is hidden.

Antec DP503 case out of the box

The size of the DP503 itself is not much different from the DP505 White. The former is only 2mm longer and taller than the latter model, the measurements of the DP503 case are 48.3 x 22 x 49.2 cm, and the type is positioned as a mid-tower case, which is also the size range most commonly purchased by players.

The overall frame of DP503 adopts a gray and black color scheme, and the overall visual effect is relatively low-key. Antec adopts the theme of a “rib” shape on the front panel, creating a multi-layered bevel height difference. Under the illumination of the light, the contrast of shadows appears. It is obvious that the front panel structure is different from the round DP505 White, adding a lot of water chestnut design, and the overall style tends to be sharp and sporty.

In addition to the unique three-dimensional shape of the front panel, a perforated mesh panel covering a large area of ​​iron is used to provide sufficient cold air intake space for the inside of the case, ensuring that when the internal hardware is in operation, the external cooling Air can enter the interior of the case to perfect the entire cooling airflow.

DP503 is a mid-tower case with 48.3 x 22 x 49.2 cm measurements.
The steel front panel has a beveled three-dimensional geometric design, and the large-area perforated ventilation design ensures air intake.
The front panel has many angular designs, and the overall trend is sporty.

The Antec DP503 on the right side of the case uses tempered glass with a thickness of 4mm. The glass uses a fog-black effect. When the power is not turned on, the hardware installed inside will be darker, which is more suitable for normal desktop use, and still want to display RGB Lighting effects, but users who don’t like too dazzling lighting effects.

The glass side panels are fixed by turning the screws from the rear without drilling holes. This design can avoid the tragedy of breaking the glass lock when fixing the side panels. A support structure extends outward from the case under the side glass. The removal method of the card tenon is pulled backward, which can prevent the glass side from being directly slipped and broken.

DP503 uses a matte black glass side panel, and the appearance of the hardware will be more low-key when it is not powered on.

DP503 adopts the current mainstream bottom-mounted power supply structure. It hides the power supply in the power supply compartment so that the power supply is separated from the cooling airflow of the core hardware. The power supply has an independent air flow to avoid the waste heat of the core hardware. The fan and water cooling radiator have seven-slot PCIe device installation positions, with reusable PCIe baffles and no cross-bar settings. The case itself does not support the vertical position of the graphics card. Players have to buy it separately if necessary. Display card vertical adapter bracket installation.

After the power supply is fixed by the rear mounting bracket, push it into the power compartment from the rear of the case.

The fan installation position above the case is pre-installed with a magnetic dust-proof filter, which can reduce dust or small objects from entering the case, causing dust to accumulate on the core hardware inside. In terms of cleaning operations, it can also perform faster and more efficient cleaning actions. After a period of use, players can use toilet paper or a dry cloth to clean after removal.

After removing the magnetic dust filter, you can see the fan installation position above the DP503. Three 12cm fans and two 14cm fans can be installed on the top of the case, and the water cooling installation supports 120/140/240/280 /360mm water cooling installation. From the top view, you can find the keyhole on the top of the case, which is more inclined to the direction of the glass side panel so that the installation of water cooling and fans can avoid the height of the motherboard and memory, so that players can install hardware compatibility better!

Pre-installed magnetic dust filters can isolate most of the dust from the outside of the case.
Three 12cm and two 14cm fans and 360/280 mm water cooling can be installed above.

The I/O interface of DP503 is located on the top of the case near the left side. From front to back are the power button, LED RGB lighting control button, hard disk and power operation indicator, two USB 3.0, HD AUDIO, MIC, USB3.2 Gen2 Type -C, the case comes standard with USB Type-C players do not need to purchase additional DLC.

The I/O interface on the top of DP503 has a standard USB Type-C slot.

At the bottom of the case is a removable dust filter at the intake area of ​​the power supply to reduce the amount of dust entering when the power supply is running. During installation, the author found that this dust filter differs from the ordinary rear extraction method but needs to be drawn to the Pushdown and pull-out. Still, during use, I noticed that the shape of the handle itself is limited, and it is not convenient to use it by pressing down directly. Therefore, it is recommended that players put the main unit down first and then remove it more conveniently.

Antec DP503 actual installation display

After reading the previous unpacking and introduction, the next step is to show you the installation effect of DP503. The installed hardware uses an ATX-sized ASRock Z690 PG Velocita motherboard and a 26.6cm long NVIDIA RTX 2080 Super FE dual-fan graphics card. It uses the included graphics card support bracket for demonstration.

The internal installation space of DP503 is quite ample. Whether it is hardware installation or cooling device support, it is enough to meet the hardware installation of current consumer-grade flagship models. In addition, the fan can be fixed on the outside of the front fan bracket, so DP503 can be used simultaneously. The upper and front 360mm water cooling can be installed.

The fog-black glass side panel will make the RGB lighting effect more low-key.
Actually, use the included graphics card support bracket.



From the point of view of architecture, DP503 and DP505 White, which were unpacked last time, are basically twin siblings. The two models are the same regarding hardware installation compatibility, including display card support brackets and accessories. The advantages are natural in the case of the mid-tower size body machine, which has very good expandability.

The largest E-ATX motherboard and two sets of 360mm water cooling installations can be installed, which is impossible for many mid-tower size cases. The DP503’s all-black structure and color matching with matte black textured glass sides allow the entire machine to be installed. It looks like a low-key style. If players like low-key but want to see RGB lighting effects, Antec DP503 will be more suitable for you!
