As already pointed out, PC-O8 utilises tempered glass for the prominent and front panels. These panels are 4mm thick have some considerable weight. Lian Li has pre-drilled mounting holes in each corner and corresponding thumbscrews are supplied which are used to securely fix the glass to the chassis. We’re pleased to see that Lian Li has provided a small indentation/shelf for this glass to fit on as in the PC-O5S we had difficulties getting the glass to sit properly. It’s great to see Lian Li employing a better technique in this execution.


Although this case does make use of tempered glass, there are also some aluminium panels which accompany an aluminium chassis. These panels do not require any thumbscrews to attach/detach – they simply clip onto the chassis which is especially helpful. These two detachable panels sit on the PSU/HDD chamber side and over the top.


Casting our eyes over the rear of PC-O8 there is a plethora of features to run through.

Over on the far-left there is an opening for mounting the PSU at the bottom with three dials to control the RGB lighting (more on this later in the review) and above this there is a heavily ventilated area – behind this panel there is a HDD cage with two 120mm cooling fans attached. The four corresponding thumbscrews fix this cage into place.

On the right-side there are a series of eight PCI expansion slot covers – each having ventilation cut-outs and there are thumbscrews for easy removal directly behind the metal cover. Above this there is another 120mm cooling fan and a filter for the top cooling configuration.


Up at the top of PC-O8 there is a small section offering front panel connectivity. This panel consists of a power button, headphone and microphone jacks and four USB 3.0 ports. In order to use all of these USB 3.0 ports, two headers are required on the motherboard.


Beyond the front panel controls there is a large spacious area – as already mentioned this panel lifts off the chassis. There is an area marked out for two 120mm fans or a 240mm radiator – this panel needs to be removed in order to install any of these devices.


Placing PC-O8 on its side there is no traditional PSU filter as the usual mid-tower would have since the PSU is mounted in a different area and orientation.

However, we do have four circular rubber feet. These feet can be removed or replaced if required as they screw into the bottom of the chassis.
