Got a replacement Dell Optiplex 755 desktop with an Intel Core2 Duo 6750 CPU with 2GB memory yesterday. My preferred linux distro is Xubuntu 11.10 currently. It requires less tweaking than the current Gnome 3.x, and has the latest Ubuntu 3.x kernel. I added LibreOffice, Chromium, Deluge, Picasa, and Nero. It comes with the excellent GmusicBrowser media player. Below are my screen shots.
