Antec GX300 Mid-Tower Chassis Review

Complete System

I had my doubts about this chassis at first, as the cable routing space looked a little tight, there’s no rubber grommets on the routing holes and the GPU clearance was too short, but in the end, it came together very well. The build was very easy to complete, although I did have to remove the top drive bay to accommodate our Sapphire R9 270X; I could have moved the bay to make it into a 2.5″ bay, but I didn’t need all six bays anyway.

Cable management is doing a great job and there are no excess cables trailing around the chassis, freeing up lots of room for good airflow. There’s certainly a lot of room in the back, good news for those who wanted to install an AIO water cooler.

There’s no obstruction in the base of the chassis either, so those wanting to fit some of the larger, high-end PSUs on the market will have no issues here.

3.5″ drives can use the rubber mounting grommets to reduce vibration, although 2.5″ drives don’t vibrate, so these can be screwed directly to the drive trays.

All panels back in place and the GX300 looks fantastic. A very nice build overall with good cable management and room for a good number of high-end components.
