Q: kernel panics mac mini mountain lion

Been having Kernel Panics on 2012 Mac Mini since September. Running Mountain Lion. I've done hardware test, Apple Store did one as well. Here's a list of things I thought were causing them:

Bad Monitor

Bad Monitor Cable

Use of USB devices, including 3rd party keyboards and mice (non-apple), hard drives and external dvd drives/writers

Time Machine

Connection to a Windows File Server

Logmein

DVD Fab

I've changed and/or deleted all of the above and am still getting them. Lately, they seem to be associated with internet surfing. Happens with Safari, Chrome and Firefox, seemingly random. But not isolated to just internet surfing. Have had them when importing pictures using Iphoto, using Itunes, or even when the computer was unattended and not being used at all.

I've also zapped PRAM, repaired disk permissions and more.

Here is my latest log:
