Why you need the Cooler Master Case EG200 for your laptop

Using a laptop without a GPU is a difficult task especially when you are into gaming or content creation like photo or video editing. A laptop that doesn’t have a GPU is only suitable for doing the basic task and playing 3D games. It is not fast enough and if you start running intensive games and software’s on a laptop without GPU it will always crash.

If you care about speed then you won’t go after a laptop without a GPU. These types of laptops are only suitable for commercial and office works. Sometimes people often buy laptops with high end specs and after a number of years the parts become outdated and worn out.

That’s where the Cooler Master Mastercase EG 200 comes in and it can help boost performance of your old laptop. if your laptop has a thunderbolt 3 port then an external graphics card can be used to increase the performce of your laptop.

It will allow new and updated games run smoothly on your old laptop. The eGPU technology is still in its early stages and it already works fine with most laptops. Most people like the comfort of moving their laptops around and with an eGPU, you can plug in and run your task.

You can unplug your laptop when you are done and move it where ever you want to. You need the Cooler Master Mastercase EG 200 because it will power your laptop if you pair it with a very strong GPU.

Selecting the Best eGPU for your laptop

Inside the box of the Mastercase EG200 you will find the EG200 enclosure with the cooler master VGold SFX 550W PSU. We have the thunderbolt 3 cable and USB type A to C Adapter. The enclosure comes with an all-black design and it is quite minimal. It is slim when compared to other eGPUS that are usually bulky in the ear.

The design is unique and at the front there Is a space where you can mount your SSD or HDD card without having to cable anything up. There is a hot-swappable drive bay located at behind the front hinged panel. we have an aluminum build here and, on the side, panels are perforated for airflow.

There is a laptop holder to the side of the external enclosure and it is very sturdy. You can be able to mount your laptop on the holder while working. Inside the enclosure, we have a mini ITX system, with a pre-installed PSU positioned at the top right corner.

We have a number of ports at the back and they include three USB type-A ports, a power port, and two GPU cutouts. The thunderbolt port is located at the back and it is at the bottom. The enclosure only supports 2 x slot graphics card just so you know.

We have a compact eGPU and the laptop stand is one of its major stand out feature and it further makes it unique. It has 550W of power it can support a number of graphics card. the fan inside the enclosure is quite large and while it is there is less noise.

Opening the box is not really difficult you only need to pull the top and side panels of the chassis. The external graphics card utilizes a tool-less design. On the bottom, the cooler masters base board is where you can install your various PCle cards.

Here are 6 key points for selecting the Cooler Master Mastercase EG200 for your laptop

Compact Form Factor

The eGPU has a unique look and the laptop stand to the side makes it look much better. It is slim and portable and can easily be moved around from one place to another. The enclosure is not as big as other enclosure that we are used to.

Laptop Stand

This came to me as a surprise seeing the enclosure come with a laptop stand. This allows you tuck in your laptop after use and it can also be extended so you can place the laptop during usage. For people that want to manage their space the laptop stand is will be useful. It can be removed because it is held by a screw attached on the chassis. While using the laptop stand you should point the exhaust side of the laptop away from the enclosure.

Cooling System

We have a single 92mm fan inside the EG200 and this helps improve airflow for those graphics cards that heats too much. To even regulate the temperature more there is a temperature sensor fitted that will act in unison with your GPUs fans, providing you with a silent idle performance or can hit 26000RPM when the card is taxed. There is a second spot for another 92mm fan depending on the clearance of your card.

Thunderbolt Connection

Now all this won’t be possible without a thunderbolt 3 port. this technology is capable of transporting 40Gbps of data from the enclosure to your connected laptop or PC. Your laptop won’t be able to utilize the power of an eGPU if it doesn’t have a thunderbolt 3 port. the EG200 is one of the few niche eGPU products that is used to bolster the performance of a laptop.


Inside the master case EG200 we have a Vgold SFX 550W PSU it will solve all the power problems of the enclosure. It has what it takes to power your RTX graphics card. the 550W is more than enough because it will only power the GPU. High end graphic cards like the RTX 3090 will works seamlessly inside the enclosure.

Swappable Storage Expansion

With the EG200 you can decide to either use an SSD or HDD card you can easily switch the cards. I prefer using SSD cards because they have faster read and write speeds. You can decide to use various storage size because there is no specific limit to the amount of storage you can use. This enclosure is probably one of the few out there with a storage expansion feature.

A closer look at the Cooler Master Mastercase EG200

There is a meshed window at the top and side of the enclosure to prevent dust from getting into the eGPU. This also makes airflow reach the external GPU that is installed inside the enclosure. This lets the laptop and the enclosure stay properly ventilated while in use.

At the front of the enclosure, you can fit in a 3.5 or 2.5 storage drive inside the case. your laptop will identify the added storage as an external storage device. it can be used as additional storage because storage never gets too much especially if you shoot 4k videos.

There are a number of important ports missing on the enclosure and they are the HDMI ports and display ports. The ports are very useful if you want to connect the eGPU to a monitor and at the price it’s selling for I feel we deserve the ports.

You can mount a number of different graphics cards inside the enclosure card of up to 325 x 54 x 141mm will sit comfortably inside the enclosure. However, you can go through forums like to find a comprehensive list of GPUs that work well inside the chassis.

The power supply conforms to the SFX size standard, if you wish to replace the power supply you can do that easily. The 550W by today’s standard is sufficient for any type of graphics card. Cooler master included that power supply to allow you to pick different types of GPU for the enclosure.

The enclosure works well on both Windows and macOS laptops but for macs, there are some limitations with GPUs. they don’t work with every GPU out there they are selective and if you plan to use this with a mac pay attention to the type of GPUs that are compatible with macOS.

Pros of the CoolerMaster Mastercase EG200

92mm fan Included – the fan helps keep the temperature of the enclosure cool all the time. The sound that comes from the enclosure is almost dead silent when idle. Even when in use the noise is not very loud and distracting. The brand also made available some space for additional 92mm fan but it depends on the GPU installed inside the enclosure.

Laptop Stand – the laptop stand is very useful especially for those that are interested in maximizing the space of their desktop. you can use it as a docking storage to safely keep your laptop. if you don’t like it you can remove it by untying the screws on the chassis that are holding it firm.

Swappable Storage drive bay – the eGPU has a space where you can add an extra storage space whether SSD or HDD. You can expand your storage space with the help of the drive bay at the front of the enclosure.

Slim Chassis – this is actually one of the slimmest chassis I have come across and it is compact with a solid build quality. It has an aluminum build that makes it sturdy.

Work with Windows and MacOS – the chassis work well on both operating systems and that is an additional advantage over others that work on one operating system. this makes the eGPU versatile.

Cons of the CoolerMaster Mastercase EG200

Expensive – this is a major issue with regards to most external enclosures it is difficult to justify the price when you have to buy a GPU separately. If you consider what you might spend on an external enclosure you will get a complete desktop PC with the same amount of money.

The external enclosure doesn’t come with a GPU if you buy it you are only getting a chassis. You have to shop for the GPU to put inside the chassis.

It is compatible with both macOS and Windows operating systems. But macOS is selective with GPU so research for compatible MacOS GPUs before buying.

Yes, you will find a thunderbolt 3 cable inside the box of the EG200.

Rounding Up

The CoolerMaster EG200 has what it takes to transform your average laptop into a gaming PC. It is a versatile eGPU with the option to even expand your storage capacity. I find the laptop stand to be one of my favorite features of this design.

If you are looking for an enclosure that will help increase the performance of your laptop then this is worth considering. The eGPU is minimal and further beautify your desktop with the aesthetic its bringing to the table.
