The Sharkoon Rebel C50 RGB offers extensive modular expansion options at an attractive price point. Four different models of the Sharkoon Rebel C50 series are readily available out of the box

The Sharkoon Rebel C50 series comprises four models: matte black, matte white, white RGB version, and the unpacked black RGB version. The matte versions come with two inbuilt PWM matte fans and mesh side panels, priced at 2490 yuan. The RGB versions are equipped with four inbuilt ARGB fans, and a glass side panel, and are priced at 2790 yuan.

Featuring a standard mid-tower power supply structure, the Sharkoon Rebel C50 stands out with its support for three 12cm fans or 360mm cooling radiators on the side. With the capacity to accommodate up to ten 12cm fans and mesh screens at the front and rear, it promises excellent heat dissipation.

The packaging, in usual black and white, ensures the case body is well-protected in a non-woven bag. Noteworthy are the included features: a USB 3.2 Gen2 Type-C, dual USB 3.0, four ARGB fans, and controllers offering 20 lighting modes.

The RGB version exclusively features a 4mm tempered glass panel, implementing a non-perforated design for added safety. It is attached with a spherical buckle, allowing easy, tool-free disassembly from the back. Additionally, black foam is adhered to both sides, providing not only a cushioning effect but also acting as a dust deterrent.

The Sharkoon Rebel C50’s rear space layout is a notable feature. A 12cm fan or a 360mm cooling radiator can be affixed near the front panel bracket. The area behind the motherboard is designed to accommodate three 3.5-inch or three 2.5-inch hard drive bays. The 3cm deep backplane space simplifies hard drive installation and cable management, proving it to be a well-thought-out design.

At the top of the back panel, there’s an 8-port ARGB hub which allows you to modify the lighting effects via the buttons on the top or through the motherboard software. The controller relies on a SATA power supply. It’s connected to the motherboard software control via a 5V 3pin connector. While the VDG 3-pin connector is rarely seen on Gigabyte motherboards, the 5V 3-pin is a common sight.

The Sharkoon Rebel C50 RGB is capable of supporting an ATX motherboard of the largest size, a graphics card up to 400mm in length, and a CPU cooler with a maximum height of 165mm. The design is modular, and when installing a side fan, the front portion of the power supply compartment and the cable management shield can be removed. It also offers an easily installable cold row bracket at the top. The case comes equipped with four built-in ARGB fans, three at the front and one at the rear.

Flexible and Adaptable Space | Measurement and Installation of the Sharkoon Rebel C50 RGB

During the installation of the Sharkoon Rebel C50 RGB, whether or not to install a side fan is a crucial consideration. If a side fan is to be installed, the front power supply compartment and the wire baffle need to be removed. The front/upper/side all support 360mm cooling radiators, but due to thickness constraints, you can only choose one among the front and side. The top officially supports a thickness of up to 60mm.

When a 360mm water cooling system is installed on the top, it may interfere with the motherboard’s heat sink. Most mid-tower cases position the locking point of the cooling row as far as possible, i.e., near the glass side, to avoid contact with the motherboard heat sink and power lines. However, the radiator bracket of the Rebel C50 is positioned relatively inside. Hence, when installing water cooling on top, you need to consider the height of the motherboard’s heat sink. Given that motherboard heat sink height are generally quite tall, the water cooling system can only be installed either at the front or the side.

In this installation test, a 360mm AIO water cooler is installed on the side with the fan expelling the air. This was mainly due to visual considerations. While fan intake and heat dissipation would be more effective, it would also make the fan bracket visible. Players could alternatively use reverse blade fans when assembling the system.

The Sharkoon Rebel C50 comes with numerous cable holes positioned around the motherboard area. However, once an ATX motherboard and power supply are installed, the holes located at the bottom and those in the power supply compartment become obstructed.

10 fans, Mesh panel blowing through | Sharkoon Rebel C50 RGB temperature test

This test uses an AMD RX 6900 XT and an Intel i7-13700, paired with a 360mm AIO water cooler. The setup is installed vertically, and the testing method involves using AIDA64 for the CPU stress test, FurMark for the GPU stress test, and HWiNFO64 to record temperature performance.

Test Platform:
Processor: Intel Core i7-13700
Motherboard: ASUS ROG Strix Z690-E GAMING WIFI
Memory: KLEVV DDR5 6200 32GB
Graphics Card: AMD Radeon RX 6900 XT
System Disk: AGI AI818 1TB NVMe PCIe 4.0 SSD
Radiator: 360mm AIO
Power Supply: FSP Hydro Ti 1000W
Operating System: Windows 11 Pro 22H2

Based on the test results, it appears that having the water cooler on the side inhibits the pressure capabilities of the i7-class CPU. While this is unlikely to reach such extremes during daily usage, it is suggested to install the front panel for heat dissipation. As for the graphics card, even though the temperature might seem a bit high, this can be attributed to the subpar heat dissipation effect of the stock version of the radiator. If an NVIDIA 40-series graphics card is used, heat dissipation should not be an issue.

With a price tag exceeding 2000, the Sharkoon Rebel C50 offers four built-in ARGB fans, a hub, and impressive internal expandability and modular design, which are seldom seen in similarly priced products. Whether it’s supporting up to 10 fans, three 3.5-inch hard drives, a 40cm graphics card, or the optional vertical graphics card holder, the Sharkoon Rebel C50 matches higher-end chassis in terms of functionalities. Although there are minor drawbacks like less than-ideal compatibility with the top cooling row and some blocked wiring holes, the flexible and diverse installation options still offer rich expandability for users.

The Rebel C50 Vertical Graphics 4.0 graphic card stand alters the orientation of the graphics card, introducing a unique assembly style. Priced at 1690 yuan, it’s not expensive considering many brands sell extension cables alone at higher prices. For users who have invested heavily in their graphics cards, this provides an excellent opportunity to show off the striking front of the card, making it a great deal.
