As of right now I am using Ubuntu 5.10 breezy badger. I find it to be a really good distro, but it just doesn't seem very customizable. One distro that I have been considering to change to is PCLinuxOS. Would it be a wise decision to make this move? Is there anything that would make one better than the other? How does PCLinuxOS handle games made for windows using wine? They are both seem to be great distros, I just can't make up my mind.

Why not keep both? If you have about 10GB for each, you can dual boot them.

And by "doesn't seem very customizable" what exactly do you mean? I use Debian (which Ubuntu is based on) and it seems infinitely customizable...

How would I make Ubuntu(that is already installed) only take up 10 gigs if I wanted to dual boot between them? And by not very customizable, I meant that the KDE desktop seemed to have more options on its preferences menus when I used the live cd, compared to the GNOME desktop in Ubuntu.

For resizing, I would download the GParted Live CD and use that to resize your filesystem. Backup any important data before hand.

As for the kde configuration options, if you like KDE as a desktop better than gnome then enable the additional repositories (or you might have to add the kubuntu repositories) and then sudo apt-get update && sudo apt-get install kde. Then you should be able to change desktops into KDE and use that instead. Alternatively, you can search your synaptic database for what you want to configure and there might just be an additional Gnome package you need to install.

Also, there seems to be an article on configuring Gnome in Tux the magazine, Issue 11 (March 2006). Free registration is required.
