THE 303 EXTERIOR
Measuring 500mm in height, 480mm in depth and 215mm in width the 303 is way above average in terms of size (for a mid-tower).
As mentioned earlier the left side panel is almost entirely made out of tempered glass (and it looks great).
To release/remove the left side panel you just need to press the handle with the company logo on it.
Just like most cases by IN WIN the fascia does not open so here we just see their logo alongside the on/off power button, reset button, two USB 2.0 ports, two USB 3.0 ports and the usual microphone and headphone jacks (all are illuminated when the system is turned on).
The top area of the right side panel is perforated (the why you will see later on).
Moving at the rear we see 7 PCI expansion slots, the PSU area and a 120mm fan.
A large removable air-filter takes up almost the entire base of the 303.
