Out of the box, the XPG Valor Air Pro looks exactly like a bigger variant of the Valor Air. The only actual difference is the fact that the glass panel spans the whole height of the chassis, while the non-Pro variant had an exposed metal shroud and shorter piece of glass. You also still get the XPG print in the front, but it is now gray on the Valor Air Pro, instead of the more prominent red.
Looking at the front, the main panel is made of steel, with diagonal cutouts which seem big enough to allow for sufficient airflow. It is held in place by a single thumb screw at the bottom and removing it reveals the three 120 mm ARGB equipped intake fans. While this is perfectly fine, the Valor Air Pro can take 140 mm units as well and including that size could have been a great way to further differentiate the Pro variant from the non-Pro version of the case. As the front panel is metal, XPG has placed a magnetic, fine mesh dust filter on it keep dirt and grime out. Its design is intended to fit perfectly as well. Looking at the enclosure from the rear, the XPG Valor Air Pro has a traditional, modern layout with the PSU on the bottom.
The glass panel is held in place by a pair of captive thumb screws. It is framed in black nicely to fit the overall hue of the chassis and XPG has wisely not tinted it heavily, so you will be able to see your system components easily. On the opposite side there is a metal panel with a similar vent pattern as the one in the front of the chassis. While this consistency is important and nice to see, these slits are much more compact, meaning that air intake of any fans you will install here will be hampered.
The PSU bay at the bottom sports two sets of mounting holes, but you will likely just install your power supply with the fan facing downward anyway. Above that are the seven expansion slots. You may rotate the whole frame of the expansion slots to allow for vertical GPU placement. Above that you will find a 120 mm exhaust fan, which is ARGB equipped at the hub, just like the ones in the front of the XPG Valor Air Pro.
In the top is a magnetic metal mesh dust filter that covers mounting holes for three 120 or two 140 mm fans. You may also install a radiator of up to 360 mm here. All the I/O has been placed on the right edge of the chassis and consists of a USB-C, two USB 3.0 and an audio combo plug. These are flanked by XPG's signature triangle power button and a smaller reset button at either end.
Taking a look at the underside, there is a basic metal mesh dust filter as well. It is unfortunate that the "Pro" variant of a case has this type of filter, as any other implementation would have been better.
