In for review is the Gamma C70 ARGB case from Ocypus – a new brand in town. The Gamma C70 ARGB offers a glass panel in a mid-tower form-factor along with four 120 mm ARGB enabled fans. The case retails for about ₱3,350 PHP – lowest I could find online.
Disclosure: Ocypus sent the Gamma C70 ARGB for the purpose of this review. The company did not ask me to say anything particular about it.

Packaging and Accessories
Ocypus shipped the Gamma C70 in a carton packaging, which is sandwiched between two high-density foams. Pretty basic, but it gets the job done.
The packaging should come with the following items inside:
- Ocypus Gamma C70 ARGB Case
- Screws
- Stand-offs
- Zip ties
- Manual
Bundled accessories to get you started are also basic.
External Design, Build and Connectivity
The Gamma C70 is offered in a clean, minimalistic mid-tower design with a dark tempered glass panel and a separate/hidden compartment for the PSU and storage devices. This is good for builds where you want to showcase the internals of your system, while still maintaining an office friendly appeal.
The rear panel on the other hand is pretty much basic. You get a blank steel sheet, which is about 0.5 mm in thickness and that is it.
Panel and its I/O ports is located at the top of the case. You get a recessed power and LED button, USB 3.0 and 2.0 ports, along with a status LED and a combo jack for the headphone and microphone. The top of the Gamma C70 also shows the magnetic dust cover for the optional 2x 120 mm or 2x 140 mm case fans.
Looking at the lower part of the case shows yet another dust filter which is for the PSU. This area also shows the plastic feet lifting the case at a modest 15 mm above ground. Another point of interest here are the screws holding the hidden HDD tray. You may remove it, or have it relocated closer to the front for better PSU clearance.
The Gamma C70 offers an adjustable 120 mm fan mount. Cost cutting is obvious around this particular area, as the case doesn’t come with reusable PCIe slot covers.
Internal Design, Build and Connectivity
The Gamma C70 is an easy case to work with, as shown by its spacious interior. We could also see how the case would direct airflow via its 3x 120 mm intake and 1x 120 mm exhaust fans.
The back showcases the huge motherboard tray cutout for an easier CPU cooler installation, along with other well-placed cutouts for cable management. I could understand why these do not have grommets, but Ocypus could definitely use a guide for the messy wiring.
Continuing the tour, there is an ARGB controller for the fan situated at the back of the case. This could be powered by your motherboard or by a SATA power cable. As for clearance, you get plenty enough for 1/2 inch diameter cables, but I suggest looking for a PSU with flat cables due to the thicker lower part of the case, where the PSU and HDD compartment meets the motherboard tray.
Clearance and Installation
Building a system inside the Gamma C70 is easy enough, unless you also account for the time tidying up the messy cables. The case is reported to fit air coolers up to a maximum of 163 mm, and the 158 mm Noctua NH-U12A does so just fine.
Cable management could definitely be better but a few cable ties here and there should do the trick. It is important to note that we removed the HDD tray next to the PSU mounting area – this is to make sure that the FSP Hydro G Pro 750 W and its cables will fit with no hassle.
Finished build with the Gamma C70 ARGB looks proper. We’ve chosen the SATA power option for the ARGB fans so it’ll only change colors based on the LED button located at the front panel.
Temperature
Upon testing, I have noticed that the Gamma C70’s 120 mm ARGB fans do not behave like normal 4-pin PWM fans do since they are practically stuck at a certain RPM range regardless of PWM values. Changing the PWM to 25% for example turns them off, whilst 50% and above nets a range of 900-1000 RPM. On that note, the results below were obtained with the PWM set at 100%.
Our test indicates excellent cooling, surpassing those observed in the previous case that I have tested.
Noise
As for noise levels, the Gamma C70 ARGB outputs a maximum of 31.9 dBA at the scale.
This is impressive, but not exactly surprising given that the fans are barely exceeding 1000 RPM.
Final Thoughts
The Ocypus Gamma C70 ARGB is a well-rounded mid-tower case that balances aesthetics, cooling performance, and ease of installation. Its clean, minimalistic design with a dark tempered glass side panel makes it a great budget option for those who want to showcase their build while maintaining an office-friendly look. The hidden PSU and storage compartment further contribute to a neat and organized appearance.
Building inside the case is relatively straightforward, thanks to its spacious interior and well-placed cutouts for cable management. However, the lack of rubber grommets and somewhat messy default cable routing means users may need to spend extra time tidying things up. The lack of reusable PCIe slot covers is also a clear cost-cutting measure along with its thinner gauge steel construction.
The removable HDD tray however is a nice touch, providing flexibility for PSU clearance when needed.
Performance-wise, the Gamma C70 excels in cooling, with its three 120 mm intake fans and one 120 mm exhaust fan delivering impressive temperature results. Our tests showed that it kept CPU, GPU, and VRM temperatures lower than those observed in previous cases tested. However, the included ARGB fans do not behave like standard 4-pin PWM fans, limiting control options—though they still operate quietly, with noise levels staying below 31.9 dBA at maximum speed.
Overall, the Ocypus Gamma C70 ARGB is a great choice for budget-conscious builders looking for a stylish and well-ventilated case. While it does come with some cost-cutting compromises—such as non-reusable PCIe slot covers, thinner steel, and basic cable management features—its cooling efficiency, quiet operation, and aesthetic appeal make it a compelling option in its price range.
