Antec GX700 Test and Review

According to the official technical information provided by Antec, the GX700 is a modern middle tower case meant for the gamers and everybody who likes a bit military design combined with great cooling capabilities and flexibility with a lot of fan slots, I/o ports and many others. Obviously, for this test and review I will have the chance to check out what the latest Antec case looks like and how it performs.


Antec GX700 arrived to me in a pretty simple and still stylish carton box with a lot of pictures and information about the features related with the product placed all over the package and technical details on the back side of the package in several languages.


Actually, this is the first Antec case which I have the honour to test and review and I was eager to check out the product itself. So after gently removing the carton box I reached this:


Antec GX700 is a case made of SECC body, top and side panels and plastic front panel with overall dimensions of 500 mm (H) x 200 mm (W) x 450 mm (D) (19.7″ (H) x 7.9 ” (W) x 17.7″(D) /) and weight of 13.8 lb / 6.26 kg. The case is painted outside and inside in black matte with additional parts painted in military green on the front side of the case.

And this is what the case looks like seen from the front/right and the right/back sides:



And this is what the case looks like seen from the front/top:


After removing the right panel I really enjoyed the inner appearance of the case and it looks like this:


As you can see from the picture above this model provides the option to use motherboards according the standards ATX, microATX, Mini-ITX and a really big CPU cutout for easy CPU cooler installation but unfortunately can’t hold very big video cards since the HDD tray is not removable.


As usual, in order for me to do a proper review, I decided to remove all parts from the case or at least those which I was able to remove without breaking the structure and describe them one by one while mounting them back together. And after I removed almost everything from the case this is what it looked like:


And seen from the back:



It took me about 15 minutes to remove all of the parts from the case and leave it in this condition. After I arranged all of the parts together  for taking a picture and before I start describing and installing them back to the case these are all of the parts provided with the black SECC body:


The case is supplied with:

  1. 2 x 140mm fans installed on the top panel
  2. 1 x 120mm fan installed on back of the case
  3. 5 x HDD/SSD brackets
  4. A fan filter for the power supply
  5. A fan filter for the front fans
  6. 8 x tool-less plastic brackets for fixing  the installed 5.25″ devices
  7. A front plastic panel with Antec plate painted in military green
  8. 4 x 5.25″ metal painted in military green brackets
  9. A lot of screws and zip-ties all painted in black
  10. A manual

Before I can do some real tests and check out how the hardware works inside the case I had to rebuild the model and install the parts and the components. It is actually a very easy job since all of the parts are tool-less and to be honest there weren’t so many of them.

The first thing to put back in the case were the HDD and the 5.25″ ODD brackets.


Antex GX700 can hold up to 4 x 5.25″ optical devices accesible from the front panel and all of them are fixed with tool-less brackets painted in black by just rotating the knob. The thing that I really like here is that actually those brackets are on both sides and not just on the left side as many other cases. So installing a DVD or Blue Ray device can be done in less than a minute. Apart from that they can be completely removed and regular screws can be used for fixing the devices.


Next thing was to put back the 5 x HDD brackets which are actually installed from the right side of the case and are made of very flexible plastic so it doesn’t break. There are no screws holes so the HDD just slides in inside the brackets and then they are put back to the HDD chassis and fixed tight to the case. Unfortunately, there aren’t any rubber dumpers to reduce the vibrations if there are any. Antec made those brackets so they can be used to install SSD or a smaller form factor drives in the middle of the brackets with screws. And this is what the case looks like when they are back to their place.


Next thing to put back inside the case was the front panel, the fan filter and the metal plates painted in military green.


The front panel is made of painted in black plastic frame with the very simple looking  (the red square) power button on the left and reset (the black square) button on the right and the green/red LEDs. The front panel can be removed too without the need of any tools.


Apart from that there are 8 x metal clips pre-installed on the front panel made to hold the four metal 5.25″ brackets which gives the case its very interesting design.

And this is what the case looks like when the metal brackets and the dust filter are back to their places:


Next thing to put back on the front panel is the metal plate which is made to hide the dust filter and provide a finished look to the front panel. The metal plate is attached to the front plastic form via four painted in black tool-less thumbscrews:


Even though there is a dust filter provided with the case, there are no pre-installed fans on the front panel of the case, which is kinda strange because like this the HDDs are left without cooling. Or at least not a direct one. Actually, between the dust filter and the HDD tray there are 2 fan slots on which 2 x 120mm fans can be installed and I believe this will boost the cooling capabilities of this product a lot.

So after I finished the front panel I had to fasten some screws and add the fans back to the case.


The case is supplied with 2 x 140mm fans installed on the top panel beneath a mesh as exhaust units, which can be removed and on their spots 2 x 120mm fans or a 240mm watercooling radiator can be installed. Apart from that there is 1 x 120mm fan pre-installed on the back of the case working as exhaust fan too. Those fans are attached to the case via 12 metal painted in black screws. And for those I had to use a screwdriver.


While I was installing the rear fan I noticed 2 things…

First is that here we can install up to 7 expansion cards, which can be fixed with painted in black tool-less thumbscrews which are hidden behind the plastic cover and the expansion slots brackets are made to be breakable like the old cases were made years ago. Actually, there are no expansion slots brackets so once they are removed they can’t be installed back and this space of the back panel will be open.

The second thing is that the back panel is made of somewhat thin SECC sheet and while I was screwing the rear fan the panel was bending. Not much but still I noticed that. Anyway, I am expecting that when the hardware is installed back in the case this thing won’t be noticeable or will completely disappear.

Actually, GX700 can hold up to 6 fans and only 3 are pre-installed. The other 3 x 120 can be mounted on the front panel behind the dust filter and on the left panel.

The next thing to point out is that the power supply is made to be installed on the bottom of the case and the fan can use cold air from the bottom of the case, while it is protected with a dust filter installed on the outside of the case which can be easily removed and cleaned, and this is what the case looks like when all 3 fans are back to their places.


There is one more thing to point out here and this is the I/O ports located on the front part of the top panel. The case is supplied with 2 x USB 3.0, 2 x USB 2.0, a mic and headphones connectors and a fan controller switch hidden under a military-type cover, which is kinda cute and provides a nice finish to the case. The fan controller offers 3 positions for LOW, MIDDLE and HIGH speed and is powered directly from the power supply via a molex connector and can control up to 4 fans directly attached via 3-pin connectors.

I believe with the fans installed back inside the case I can proceed and install the hardware and do some testing…

I believe now is the moment to say that for this test I will use my brand new Antec HCP-750W, which is a really nice and impressive product.


And this is how the case looks with all the hardware installed:




After mounting the hardware inside the case, I decided to measure temperatures in idle mode working at standard and overclocked frequency and at full load at standard and overclock frequency of the CPU, SSD and the video card.

For this test I used my standard hardware with one new part:

CPU: AMD Athlon X4 620 at standard frequency of 2612 MHz and overclocked at 3640 MHz (at 1.5V) per core for the tests.

Motherboard: GigaByte 790X-UD3P

Video card: Sapphire 5830 Extreme 1GB DDR5 256bit at standard frequency of 800/1000 MHz and overclocked at 900/1100 for the tests.

Memory: 2 x 2GB Apacer 800 MHz

Hard drive: Kingston SSD SV100S264G

Case: Antec GX700

Power supply: Antec HCP-750W

Cooler: Cooler Master Hyper 212 Evo

Thermal paste: Gelid GC-Supreme

Fan mounted: The standard 120mm fan from the Hyper 212 Evo package working at ~ 1600 revolutions per minute.

The tests were conducted in a closed system with:

  1. 120mm fan on the back panel working as exhaust fan at ~1000 revolutions per minute.
  2. 140mm fan on the top panel working as exhaust fan working at ~1200 revolutions per minute.
  3. 140mm fan on the top panel working as exhaust fan working at ~1200 revolutions per minute.
  4. Room temperature of about 17 degrees.

My working environment looked like this:


After I was done testing, here are the results I measured.

Test in idle mode of the CPU at 2612MHz, the video card at 800/1000 MHz and the SDD.

Antec GX700 @ 2612 Idle

Test with full load of the CPU at 2611MHz, the video card at 800/1000 MHZ and the SDD.

Antec GX700 @ 2612 Stress

Test in idle mode of the CPU at 3640 MHz, overclocked video card at 900/1100 MHz and the SSD.

Antec GX700 @ 3640 Idle

Test with load of the CPU at 3640 MHz, overclocked video card at 900/1100 MHz and the SSD.

Antec GX700 @ 3640 Stress

After I spent some hours doing the review and the tests I finally got at the part to share my thoughts about the case.

  1. Antec GX700 performance  – even though Antec GX700 is a middle tower case, it provides a very nice and very decent performance. The thing that surprised me the most is that even without the front fans pre-installed  to provide cold air to the airflow inside all of the hardware was working at normal temperatures even at the OC tests and I was able to feel with my hand the speed of the air going inside the case through the holes. While I was doing the tests all of the parts were cool enough and working in a very stable way which made me think that the case does the job for which it was built. The thing that made me worried a bit from the moment when I installed the rear fan, which was the thin back panel and possible bending, disappeared when I installed all of the parts inside the case and later it was one really stable and strong case.
  2. Antec GX700 noise level – as usual for all my tests I use all cooling fans working at maximum speed to provide maximum performance and in that case the fans were a bit noisy when working at maximum speed but when they are automatically controlled by the motherboard they rarely reach high revolutions per minute and they work at low noise level.
  3. Antec GX700 appearance – Antec GX700 is a case made to provide military style painted in black/ military green colour scheme focused on the gamers which on the first sight is not the most beautiful thing but after I got used to it I found it very attractive. After all I was a HAF 932 user for a long time and I am kinda used to cases with similar edgy designs.

Before I finish this article and give the reward for Antec GX700 I should say that I strongly recommend installing at least one 120mm fan on the front panel to keep the hard drives cool and provide fresh air to the airflow inside the case.

I think Antec GX700 deserves the following reward:


Official price (MSRP): Antec GX700 – unknown

Warranty: unknown


I thank Antec for the test sample.

    From what I saw on the USA markets the price is about 60 usd. For that price we saw 3 fans, fan controller, up to 4 x 5.25″ and 5 x 3,5/2.5″ hdds and I believe it is a great deal.

    And yes the red button will be very attractive to kids or small hairy animals 😛

    I noticed only one problem that later got fixed when all parts were installed and that was the thin secc of the back plate. After all this is a budget case for gamers. Lets not forget that 🙂

    Looks like a mixed bag to me..

    Antec quality but some minor things missed though (like one more fan and thinner plate at the back)..

    Simple look (which is a plus for me), but not that clean.. (and especially for me the red Power button.. I can easily see how my kids will specifically target it 😀 ) I would also prefer the 5.25 brackets to be painted black..

    The interior.. looks well thought of (like the whole on the back for accessing the CPU brackets) and entirely painted black.. I don’t see Dk_vr mentioning problems with it..

    So it seems it would be down to cost.. if it is right.. the product would easily appeal to non-pretentious enthusiasts.. am I right DK?
