I am running 2 PC boxes with Linux Mint 6 Felicia Xfce on each.
Here are their screenshots with links to full size:
My second box, but first to go Linux
My main box, which I recently scrubbed Windows XP Pro from.
Both systems were built by Cyberpower over 4 years ago, and run AMD 64bit processors (Linux install = 32 bit).
Making the move from Windows to Linux was one of the best decisions I ever made.
Unfortunately I still have to experience Windows at my workplace, both as a user and as IT. Oh well, experience it is.
Yes, I am a geek.
