The Antec P380 is one of the best chassis I’ve ever had the pleasure of working with. The installation process couldn’t have gone any smoother and as you can see in the picture below, even a full ATX motherboard, a high-end power supply and a pair of Sapphire R9 270X graphics cards, with their huge Tri-X coolers, barely fills the interior of the chassis.
Dependant on your motherboard’s configuration, you could easily fit three graphics cards into the P380.
At 308mm long, these cards are hardly small, but there’s still a lot of room to spare without having to remove any of the hard drive bays.
The chassis is huge, so without using cable extensions, I had to bundle the excess GPU power cables in the base of the chassis. Although, there’s enough space here that it doesn’t look cluttered.
Motherboard clearance at the top of the chassis is very good, more than enough room for a slim radiator in the top and there’s a few extra cable routing holes at the back to deal with any additional fans you install.
All panels back in place and the P380 looks even more incredible! The side panel window gives a great view of the systems interior and there’s no doubt that this is a great system for showing off your rig.
The overhanging aluminium top and front panels do a nice job of hiding the I/O panel and power buttons; giving you a clean look from the top and front of the chassis.
This chassis is big, bold and most certainly beautiful; a very clean and tidy build overall.
