Antec GX300 Mid-Tower Chassis Review

Antec is one of the most recognisable names in the chassis industry. They’ve been around longer than I remember, long enough that my first self-built system used an Antec chassis. With that in mind, I’m very happy to see another Antec product in the eTeknix office today – the GX300 mid-tower.

The GX300 is designed for gaming systems and it comes equipped with all the features you would expect from a good mid-budget gaming chassis. You’ve got a large side panel window to show off your system, room for multiple graphics cards, loads of storage and a slightly aggressive exterior design that should no doubt appeal to a lot of gamers.

It’s also available in a range of colours to best suit your needs/taste and while we have the black model in for review, you can also get it in white with black trim, or orange with black trim.


As you can see, we’ve got a huge side panel window on the left of the chassis, as well as a small GX300 badge in the bottom right corner. The window has a very strong tint to it, so it may be hard to see your system, unless you have a GPU or other hardware that lights up.


The right side panel has a large raised section, this will provide us with a lot of extra space behind the motherboard for cable management.DSC_0311

The front panel has a rather unique design and while there is a lot of plastic here, it’s still very nicely finished overall. There’s plenty of ventilation at the front, which should provide any front-mounted cooling with the airflow that it needs.


Around the back, a pre-installed 120mm fan and seven reusable ventilated expansion slot covers; more than enough slots for a multi-GPU configuration.


There’s a large air filter/vent on the top of the chassis, which is perfect for any top-mounted fans.


Towards the front, you will find a recessed section that can be used to store spare flash pens, screw, coins that you found in your pocket – whatever really. There’s a slider for the built-in fan controller on the right, a pair of HD audio jacks, a really nicely designed power button and the usual USB ports. What is strange is that one of the USB ports doesn’t exist, there’s just a plastic filler.


On the base of the chassis, you’ll find a durable set of stands with firm rubber grips on the base. These feet provide the GX300 with good ground clearance, so airflow to the PSU mount at the back should be pretty good. There’s a clip-in mesh filter for the PSU, which isn’t the best, but certainly better than no filter at all.
