Unfortunately, the motherboard tray isn’t removable but there is still plenty of room to work with. The P-180 comes to you with the motherboard risers pre-installed for a standard ATX motherboard. I hate installing these things.
The 3.5″ drive bay is a fantastic compliment to the overall quality of the P-180. There are two FANTASTIC features about this caddy that really elevate this chassis to an upper echelon of computer chassis. The caddy is installed and sits in a unique system that makes installation proper the first time. Too many times caddy’s rest in metal guides that are shoddy and horribly designed. This system is a perfect compliment to the detail of the P-180. Not only does Antec go beyond the call of duty with the installation of the caddy, they also provide you with a place to store all your screws and small items associated with your case on the back side of the caddy. This means no more fumbling around looking for screws to install stuff. This is really one of the best designs I have seen in a LONG time. Oh, I almost forgot to mention, there is room for a fan incase you decide not to install your components in this caddy. Pardon all the pictures, but I was very excited about this.
The caddy implements the removable tray system we have seen in other Antec designs but goes a step farther with its installation. Each tray uses silicon grommets to reduce vibration from your hard drives if you choose to install them in the upper portion of the chassis. The system is simple and effective.
