It's time for a new dev box. I want to dogfood Windows in the JS pit, and I'd like to be able to do replay debugging, so I think something with the same specs as the box in bug 534342 is the way to go. OS should be Windows 7 64-bit as well. Let me know if you need any other details.
Your current desktop looks like it's only about a year old, so this will need to be approved by damon and mrz.
