Windows terminal setup

Hi

I was wondering if it would be possible to run a server to update 5 ageing
clients. they are becoming slow and I was thinking about buying a new
1000mhz+ computer to take over the processing of the other five, using
terminal server.

my question is, would the clients still be able to play MP3's
simultaneously, watch DVDs and DIVX movies and play games like the SIMS if
there were installed on the main machine.

also can I install some sort of terminal services client onto the windows
95,98,2000 and XP so as soon as the system boots they get a terminal desktop
CTL ALT DEL login box

Thanks for your help

Max.
