I would go for a 2 - 4 64bit CPU (AMD/InTEL) with 8G RAM.

Let them live in a MS2003 terminal server and then access them using rdesktop from the central Linux box. Be careful, though. Do not expect miracles with sound and video. If that's what the school really want, sell them the idea of a separate room (multimedia room) with MACs running all fancy multimedia stuff. My recommendation is to VERY stict about what MS software to actually run. In my experience, nearly all sw have very fine if not better OpenSource equivalents. I've setup many schools, I've always achieved the best results from the 100% Linux schools. My attitude is like this; this is a Linux setup, if you think MS i better then go for it by all means. Just don't ask me to set it up. I've had the best successes in the places where I've been very strict about this. > > Thanks for comments and facts ;-) You're welcome. > > Tor > ------------------------------------------------------------------------- Med venlig hilsen/Best regards Verner Kjærsgaard ------------------------------------------------------------------------- Take Surveys.
