Patchworks Level ITG White/Grey:
I have this same case on my silver X. Bought it as a temporary hold over until my RhinoShield Mod arrives since it was only $4 after a coupon I found on Slickdeals. I've gotta say, I had low expectations given the price but I'm really impressed with how well it fits.
The X fits very snug inside the phone and I feel absolutely no give anywhere. Perfect fit. It also definitely offers a good amount of protection from drops and has a fairly tall lip to protect the screen. The lip extends across the bottom of the phone too, but it hasn't prevented me from accessing the gestures in any way. Camera is slightly recessed in the case so no concerns about it getting scratched when lying on a table. All the cutouts on the phone are perfectly aligned.
The buttons are protected but offer great tactility. I can still clearly hear and feel the click of the side and volume buttons, which I like since I've never liked cases that make the buttons muted or feel vague in that I can't tell if I've clicked it or not.
The mute switch is fairly recessed into the case so you must be very intentional about flipping it. Can't just use the pad of your thumb... Gotta get in there with a fingertip/nail.
The case itself looks decent as well, with an embossed logo on the bottom left corner and the word "Patchworks" along the bottom left side (beneath the volume buttons). The case certainly hides the beauty of the phone itself. But that, sometimes, is the price of protection.
Edit: should also add the case has a spot to place a magnetic plate for those (like me) who use magnetic mounts in their car.
