Last week I upgraded my motherboard and cpu, a yearly ritual for me now. Arch Linux is now the main system that I run on this desktop. Gentoo/Funtoo will be there for testing (Funtoo is really fun to play with). I will also test Pardus, a Turkish linux distribution. It may be a good distro to use in the educational setting.
Below are some pictures of me adding the new hardware:

(After I installed the new core 2 quad cpu and 4 Gigs of RAM)
