Delete KDE Programms

Sure is. You just need to figure out what package(s) you want. Then you can use e.g. apt-get or aptitude to install them. Say after a netinstall with no graphical interface selected.

The "triskel" package provides a good base (i.e., basic applications including Abrowser and KDE applications you probably want: the Plasma desktop, the file manager, the virtual terminal, the PDF reader, etc.). You can then install your applications of choice (a text editor, a multimedia player, an email client, an office suite, an RSS client, etc.) on top of it.

There is "triskel-recommended" too if you want a whole KDE-based desktop environment (including the applications I suggested you to choose one by one).

The NetInstaller provides you a truly minimal system. A working terminal. APT is functional too. That means, you can then 'sudo apt-get install' any package after the install. Including "triskel" and "triskel-recommend".
