Antec GX300 Mid-Tower Chassis Review

Interior

The interior of the GX300 has been treated to the same powder black finish as the exterior, giving the chassis a nice uniform appearance both inside and out. There’s a good size cut-out behind the motherboard to aid with CPU cooler mountings and there’s a good selection of cable routing cutouts around the motherboard area.

There’s room for a pair of 120mm fan in the top of the chassis, although not much hope of water cooling as it would likely conflict with the motherboard. However, you could easily manage a 120mm AIO in the rear fan mount.

Four small anti-vibration pads for the PSU.

A 120mm blue LED fan in the rear.

The hard drive bays are split into two sections. The bottom ones are fixed, but the top three can be adjusted. The left side wall of the top bay can be moved inwards to create dedicated 2.5″ bays, or be removed completely to free up extra space for extremely long graphics cards.

There’s not a lot of space around the back, but keep in mind that the right side panel has a raised section, which should free up more than enough room for excess cables.

There’s a rubber nub behind the motherboard, this will press against the side panel and help prevent it from vibrating. There’s also a bunch of cable tie down loops here, which should further help with keeping things neat and tidy.

Behind the front panel, you will find a single 120mm blue LED fan, much like the one in the rear of the chassis. There’s also room to install a second 120mm fan should you need the extra airflow.
