Assembly

Adding a motherboard is done by using spacers and screws. As I use be quiet! coolers, I was unable to utilize the larger 120 mm towers as they were just a tad too big for the 155 mm limit. Thus, I had to install the only other cooler I had at my immediate disposal. If planned well, you should be able to find plenty of 120 mm tower coolers that fit within the confines of the PC-O11 Air; however, this goes to show that the enclosure is really geared towards a liquid-cooling setup—if that was not already apparent at this point.


The SSD on the floor of the chassis may easily be installed outside of the case thanks to the removable drive tray. Once put back in place, its connectors line up perfectly with the slim opening along the bottom edge of the chassis.


The two metal drive trays in the opposite compartment may hold both 3.5" or 2.5" drives. Once filled, simply slide the trays back into position until you hear and feel a snap. The connectors may easily be reached to add the appropriate leads.


Installing the PSU is pretty straightforward. Simply place it down and use the included screws to secure it. You should really install it before adding hard drives to the central plate as it makes cable management and routing so much easier.


With everything installed, the main compartment looks extremely tidy. Even though we are not using any radiators inside the case, all the areas within the chassis where fans or radiators may be mounted are completely clear of any cables. Even the backside of the motherboard tray is nice and tidy due to the central plate covering it all. Lian Li could have opted for a window here as well, but naturally chose all metal as it is the only material to easily allow for the addition of air vents.
