Antec GX 1200 – Test and Review

Antec is one of the companies that takes special care of chassis line ups and they have a vast majority of cases coming in different varieties, sizes and feature packs. One of their most famous product line ups is the GX series cases oriented at those who really want to revamp their gaming experience and enclosure.

Without further ado, please have a look at our previous test and reviews of Antec cases. You can also use the site search to check out other tested and reviewed products of Antec.






Today, I have the pleasure of familiarizing myself with a special case emerging from the GX line up and making a statement.

I give you Antec GX 1200 gaming chassis.

Let’s have a closer look at it and in the article below I hope you find your decision easier whether your chassis needs changing.

Standard packaging Styrofoam/nylon protection
antec-gx1200-1 20161210_113722-2


Package wise the case comes in a not so large carton box made of recycled paper and internally the styrofoam is well suited for the weight of the case. As light as it is at 5.5 kg it came in one piece, there was no structural or cosmetic damage to it.

Frontal side of the package focuses mainly on a slightly distant photo of the case and large text states the name of the product. A thin black lining on the right side contains the company name and additional information. Standard specifications and technical bits are printed on the remaining sides of the carton box.


Antec gx1200 EXTERIOR

With this case, Antec are aiming to get the attention of gamers who are on a budget, however the desire to own a beautiful case is present and without robbing a bank you can have a very sleek looking chassis to house your hardware, be it low-end or high-end.

Special effects and handy features are included in GX 1200’s portfolio, but more on that later in the article. Let’s now focus on examining the exterior of the case and checking out its design.

Being a mid tower gaming chassis the dimensions are standard for the range, 520.7 mm (H) x 203.2 mm (W) x 520.7 mm (D), a bit on the narrow side I must admit. Nonetheless being a narrower case, GX 1200 appears to be taller. This comes mainly from the way it’s designed from the front.

Without protective materials Front section

The slightly indented frontal mesh grill widens up moving bottom to top and creates that sense of completion when it hits the rear top end of the chassis. Nice curves all around and you have a great looking stylish case.


On the other hand, several vents to aid passing air from the interior, serve as additional greatness to the overall design of the case.

Left side panel has been developed with an acrylic window, square in shape and flat with the panel. It’s very nice to see this included in a budget case, having your hardware visible on your desk creates a bit more expensive feel.

Bottom portion Rear section
20161210_114133-8 20161210_114122-7


Bottom side of GX1200 houses the rubber feet, which are nice and they do the job fine, however due to the light weight nature of the case it doesn’t really provide much anti-slip confidence on the surface I have at home.

Rear section is as standard as it gets, additional air vent holes are present and the PCI covers are also vented.

This was a brief overview of the case’s external presence, now let’s move forward to the interior section where the beauty really comes from.


Antec gx 1200 INTERIOR

Undoing two thumbnail screws will grant you access to the interior of GX 1200, even though it’s mostly visible through the well executed acrylic window.

As most cases nowadays the interior is painted with the same color as the entire case, very well done I have to say. Another quick spot is the metal housing on the bottom that covers most of the case. This is the chamber which houses the PSU and could also do so for the storage devices you might install there.

For the price range I would have expected at least two or three rubber grommets at least – this would have added additional value in my opinion.

A small black box on the left top corner is used for the light effects so stay tuned for that in the next portion of article.

Internal layout of GX 1200 can be installed with mini ITX, micro ATX and standard ATX motherboards. The GPU maximum length can be up to 410mm which is quite impressive. No mention for CPU clearance in the official website.


As you’ve noticed a small and transparent nylon bag contains all the usual additional accessories for a chassis. A few non-reusable zip ties, labeled screws and a user manual (informative and concise) are the main ingredients. Not too shabby. All screws are painted in black and the labeling is a great helper for those who might be wondering which screw to use for a given part while assembling.

Now that I’ve checked most bits of the case it is time to disassemble it and have a look around the chassis’ design and its structural integrity.

It’s quite an easy task to get to bare bones and realize that the case is built very good, structurally durable. One of the main strengths comes from the metal shroud covering the bottom portion of GX1200. It is riveted so removing without damaging the case is not possible and there is no need to ever remove it. At certain spots of the chassis the steel is quite thin, but that’s no hindrance to the overall solid design.


Here is a quick list of the removed parts and accessories:

  • 2 x side panels
  • 1 x top plastic panel
  • 1 x front plastic panel
  • 2 x 120mm fans
  • 2 x 3.5″/2.5″ drive mounts
  • 1 x metal SSD bracket
  • 1 x PSU dust filter
  • 1 x LED/fan control unit (Antec Magic Box)

I will now begin to assemble the case back together so you can have a better idea of how it’s all possible and explaining the process.


Made of plastic, the top panel is held into place with plastic clips, very easy to remove and install actually. It’s also holding the PCB of all buttons as well as I/O cables.

  • 1 x Power Button
  • 1 x light switch button
  • 2 x HD audio 3.5mm jacks
  • 2 x USB 3.0 ports

Clipping it into place with gentle force and we’re good to go. Let’s move onwards to the fans.

2 x 120mm fans installed Closing of front panel

Installing the included fans is a straight forward job. Those two samples of 120mm fans are quite interesting and serve a greater purpose than just cooling.

Rubber insulation on the screw holes makes them more premium and also prohibits vibrations passing through to the metal chassis, thus reducing the output of noise. Excellent move. Both fans however have control button on them to enable individual color settings and you need to connect them to a motherboard fan header.

Additionally GX 1200 can be equipped with more fans and supports water cooling radiators as well.

  • Rear Radiator: 120mm x 155mm x 45mm
  • Top Radiator: 240mm x 120mm x 30mm
  • Front Radiator: 360mm x 130mm x 40mm

Optional fan positions:

  • Front: 120mm x 1
  • Rear: 120mm x 1
  • Top: 120mm x 2

All in all it’s 120mm mounts throughout and even though it may not sound like much it’s a great way of having small sized fans due to most 120mm being with faster air speed. In a narrow case that would mean better cooling.

Fans can be connected to the Antec Magic box and their LEDs controlled from there. Its held into place with  four small screws and can be mounted at the top (as in the picture) or lower, depending on the cable length. Control over the fan voltage can be done from there – 5V, 7V and 12V. Along with control of the actual lighting effects. It’s a bit on the inconvenient side as it would have been great to have another button on the top panel to control fan RPM.


Installing the front panel is quite easy once you install the fans. It’s got several plastic clips and snaps into place with ease.


Before moving forward I would like to point out a couple of things that I’ve noticed throughout the reassembly process and they revolve around the quality of plastic used and the finished look.

Top panel right side Front/top panel right

As you can see from the photos it’s quite visible that either the quality of the plastic and the molds themselves aren’t of the highest quality. Additionally the Quality Assurance checks for a company like Antec are expected to be better. It’s really not a huge deal and is only visible up close, but it’s definitely worth the note.

Let’s move forward to storage and what GX 1200 has to offer there in terms of mounting points.

2 x plastic HDD/SSD mounts 1 x SSD dedicated mount
20161210_122312-22 20161210_122337-23


The total amount of drive bays is five and 2.5″ drives are more welcomed than 3.5″ones in this setup. Under Antec Magic box you can install 2 x 2.5″ drives and 1 x 2.5″ on the metal bracket behind the motherboard tray.


Two plastic rails are responsible for the heavier 3.5″ drives, which are also 2.5″ compatible. Rubber mounts are available there to dampen any vibration from high performance HDD so that’s quite a good feature.


Last thing to install was the PSU dust filter located on the bottom of the case, along with the sliding side panels. The case was now ready to be installed with my test system.


Antec GX 1200 TESTS

For the testing I will use an Intel based system with Z97 chipset motherboard.

Intel Z97 Test system

  • CPU: Intel i5-4670K
  1. At standard frequency 3.400 MHz (Voltage set to Auto when not OC-ing)
  • Motherboard: ASUS Maximus VII HERO Z97
  • Video card: MSI AMD R9 280X GAMING 3G
  • Memory: Kingston Hyper-X SAVAGE 8 GB, Dual channel, 1866 MHz
  • Solid State Drive: Intel 530 Series, 120 GB
  • Hard drive: Western Digital 1 TB RED Series, NAS
  • Case: Antec GX1200
  • Power supply:  Corsair RM750 W
  • Cooler: Cryorig H5 Ultimate
  • Thermal paste: Cryorig CP7

The test was conducted in a closed system with:

  • 2 x 120mm Antec fans, rotating at maximum RPM at 12 volts, mounted at the front
  • Room temperature of about 21~22 degrees Celsius.

And here I want to describe my testing method.

I will install my test rig inside the case and do CPU and VGA stress tests using AIDA64 for about 10 minutes with these settings:

  • CPU: Intel i5-4670K – At standard frequency of 3.400 MHz (Voltage set to Auto when not OC-ing)
  • MSI AMD R9 280X GAMING 3G – running at stock voltage and auto speed control of the fans.

Antec GX 1200 is a case that enables you to easily built your system inside and tackle cables with no issues. The metal shroud also provides good amount of space to hide cables and connectors if they are not needed and keeps the built nice and tidy, pleasing to the eye.

Very clean looking interior I have to say, barely noticeable lack of rubber grommets and here is a shot of the acrylic window that makes the case stand out.


Here is a summary of the tests:

After I’ve spent several hours disassembling, assembling, reviewing and later testing the case, I believe it is time to express my thoughts on the product.



1. Antec GX1200 performance – It’s very well built case with just a few minor exceptions. I really liked checking the chassis and seeing its features that all in all sum up to quite a good and competitive option if you’re in the market for a  gaming case with special effects. Definitely there are things to consider when buying this one – LED lights, fan controller, metal shroud to keep things nice and tidy, great visuals, expandability, water cooling support and the overall value of the case. My opinion of the tests is positive given the fact that there are two front fans only. Moving forward and occupying all slots or having water cooling radiators installed – GX 1200 will impress you.

2. Antec GX 1200 appearance – Main selling point of the case is its LED lights and effects – seven different colors and four different modes (color changing, pulsing/breathing, blinking, and fading). Have a look at the photos below and decide for yourself. Uniformity of the light along with the different modes is superb (even at mid day the lights are easily visible). Acrylic window puts your hardware on a display and the lights actually shine through it, almost as a shadow. Interior is also lit nicely to give the case that complete look of a well built and good looking PC.


3. Antec GX 1200 noise level – Integrated fan controller, 2 fans included our of the box – not the noisiest case I’ve reviewed. At 12 volts the noise coming from the front fan is prominent as well as the air speed. Would you keep the fans at 12 volts all the time – I doubt it, especially if the PC is right next to you. The acrylic window is not good at dampening noise as well due to its materials and that;s just how things work. Gaming rarely goes hand in hand with silence. Keeping the fans at 7 volts is quite acceptable and the case is near dead silent. Having the LEDs around makes the environment quite settling.


I believe Antec GX 1200 deserves the following reward:


Official price (MSRP) for Antec GX 1200: unknown euro

Warranty: unknown

Special thanks to Antec for providing us with a test sample.

  1. Does Antec liquid cooling mercury 360 can be fitted in front for this case?

    • Hi Gugan,

      Antec’s Mercury 360 water cooling solution is with physical dimensions of 394 x 119 x 27 mm and theoretically can be installed in GX1200.

      In the front GX1200 has space for 360mm x 130mm x 40mm radiator. Even though the Mercury 360 is 34mm above the maximum allowed height there is enough space for it.


  2. Hi, I’m very interested in buying one of these cases, I’m going to run a full size radiator up front I think but I want to purchase more of the fans that are included in the case. Are these available to buy separately?



    • Hello Jay,

      Thank you for the question.
      Anyway I believe the best thing to do is to contact directly Antec and ask them if the fans are sold as a stand alone products.

      Best Regards

    • Hi Jay,

      Thanks for your comment.

      To be honest I’m unsure whether exactly the same case fans are available for aftermarket purchase, but you can check in Antec’s website (depending on your region) – http://www.antec.com/index.php?page=cookieSet.

      There are plenty of models with RGB lights and also the Magix box will allow for some control over them.

      Hope you find your most desired fan 🙂


  3. Hi, I see you fit the cryorig h5 CPU cooler in the case, was wondering how much more room there was? Would it fit a noctua 15?? They are 165mm to the cryorig h5 160mm.
