The case comes with plastic drive rails for mounting any 5.25" devices. Depending on the type of device, you'll use one of two sets of holes in the rail. One will mount the device flush with the front bezel, while the other will mount it back slightly. The latter mounting option works with the special optical drive covers that occupy the P160's top two 5.25" bays.

One complaint here: The drive rails came loose in a box with the rest of the motherboard standoffs, screws, etc. In the past, Antec has done a better job of keeping the rails with the case so one doesn't misplace them. Given the P160's trick optical drive bay covers, I don't really expect rail storage inside the drive bay covers like the Sonata, but would it have been too much trouble to store them in the bottom of the case ala the SX-1030?

I suppose storing the rails on the bottom of the case would clutter things up if you had a case window, but we're talking about a case that comes standard without a window. If you can handle putting a window in, you can handle removing storage brackets for the drive rails. For that matter, they would probably fit on the other side panel, "behind" the 5.25" bays. Then they'd be out of sight, out of mind, and if one needed more rails, one could just pull the other panel to get to them.

The P160 counts a removable motherboard tray as one of its many features. This isn't exactly the best photo I've ever taken, but it hits the highlights at least. In the upper right corner, you can see the track on which the motherboard slides in and out of place. Midway down is the thumbscrew that holds the tray retainer in place. Once the retainer is removed, the tray slides back and out. Directly above the retainer is a handle to aid removal of the tray. Look at the next picture for a better view of it.

Here's a shot of the tray outside the case. The handle and the frame for the I/O shield make good grabbing points when pulling the tray out.

Here's a nice touch. The rails on which the motherboard tray rests have soft plastic inserts in them. The inserts are slightly higher than the surrounding metal, which ensures that no vibrations from, say, a CPU fan are transmitted to the rest of the case.

In his Antec Sonata review, Damage lamented the lack of thumbscrews for the PCI and AGP slots. Then, Antec releases the P160, which comes with... thumbscrews for the PCI and AGP slots. Coincidence? You be the judge. Note also that the P160 uses spring-loaded slot covers, rather than blank covers held on by the screws.

In another noise-reducing move, the 120mm fan that mounts in the P160's rear fan port uses rubbery grommets to hold it in place rather than screws. Again, the idea is to isolate the fan's vibration and keep it from spreading to the rest of the case.
