The windowed side (with the protective film in place) has three indentations, mimicking the louvers in the bezel. The acrylic window is quite large and is held in place by screw-type fasteners. At the top are two latches and the panel is removed by turning the latches and pulling the panel out from the top, then up, to free it from the case. The rear latch has an integral locking feature.
Here is a shot of the latches from the inside. They are very sturdy and hold the panel securely. As a side note, the P160W secures its panels and some other components in an unconventional, counterintuitive manner, and a careful read of the manual will prevent inadvertent damage during disassembly and preparation of the case for a system install.
With the panel removed, the interior of the case presents some interesting features that we'll go over in more detail. Although the P160W is all-aluminum, the chassis is very rigid and the edges are rolled to prevent those annoying little cuts that can occur when working in a poorly made case.
As you may or may not be aware, my associate Mr. Bones is very fond of looking at his own reflection, and the chrome frame of the bezel provides an excellent opportunity for this proclivity. Just to his left, is another security feature of the P160W. With the side panel in place, a round pin slides into a ring connected to the front bezel. This prevents the front panel from being removed unless the side panel is open.
At the lower front, a captive thumbscrew holds the front fan holder in place. As we'll see, Antec has used this captive screw design in several places in the P160W. This feature keeps the screw with the device even after the device has been removed, thus preventing those pesky computer gremlins from hiding them. In many chassis' I've looked at in the past, installing a fan in this location can be troublesome. This is a great feature and fan installation couldn't be easier. Antec has also done a great job with the HDD cage. Individual trays, with rubber mounting features are easily removed and replaced via the attached rails. At the top of the photo is the 4-pin pass-thru connector that powers the front lighting.
Near the top and just behind the drive cage is a bracket, complete with captive thumbscrew, which secures the removable motherboard tray. With the bracket out of the way, one merely grasps the attached handle (just above the bracket) and slides the tray forward and out of the case. Steel inserts in the tray accept the included brass standoffs for the motherboard. Without these inserts, cross-threading or stripping the soft aluminum could be a real problem.
