My 'modern' PC (a 6-year-old early dual-core laptop) is running a frankenstein install of Mint 13 that I'm constantly tweaking. It was originally an XFCE version of Mint but I pulled in KDE 4.10.5 from the Kubuntu repos and am using the theme from another distro, KXStudio. I also run Awesome WM occasionally, mostly fullscreen stuff where I don't really need a desktop. I upgraded the kernel to 3.8.0 (<-- don't do this! HUGE pain in the butt!) and excised the original PulseAudio system for ALSA, as well as various other backported upgrades and changes. I do a ton of stuff (e.g. most of my file management) from the console so I run Guake to get an instant dropdown terminal.
BTW I've got a second monitor "stacked" vertically over the laptop display, for a combined screen of 1280x1824, or 16 x 22.8 aspect ratio... yes, it's weird, but it gives me a nice amount of screen space taking a relatively small amount of desk space. I should get a picture. I love this setup now that I'm used to it.
