Antec P9 Windowed Mid-Tower Chassis Review

Complete System

Working with this chassis was nice and easy, and it was immediately apparent that it was very well made. All the panels and interior components are thick and durable, with heavy metal components and tough plastic fittings, such as this hard drive dock. First things first on this build, drop in our SSD, you can remove this bracket if needed too.

The final build looks neat and tidy, a little cable trail for the GPU, but that’s more the fault of the GPU design than the chassis.

There aren’t any cable routing grommets on the cut outs, but everything still looks neat and tidy, and the black PSU cables blend in well with the black interior of the chassis, giving it a more clean look overall.

Our large GPU fits just fine, and width certainly isn’t going to be an issue here, so even if you have extra water cooling blocks and tubing, you’ll have more than enough room to work with.

The 270X we use is quite long, so I was forced to remove the top hard drive caddy, but that’s not uncommon on a mid-tower for such a long card and there are still 6 HDD bays left; more than enough for most builds.

CPU cooler clearance is excellent, and there’s a reasonable amount of room above the motherboard too, giving you room for extra radiators and fans in the top of the chassis.

Well-placed cable routing holes near the motherboard help keep things neat and tidy, and there is easy access to the rear mounts for water cooling pumps/reservoirs.

Overall, a pretty clean-looking build and more than enough room for the kind of hardware you would expect in a mid-tower gaming system build.

Finally, the side panel window back in place, and that crystal clear panel gives an uncompromised view, making ideal for those eager to show off their hardware.
