It's probably best to avoid the abreviation LTSP (Linux terminal server
project) as the LT might suggest something to do with laptops. Your full
explanation, is probably better, perhaps with a little modification.
Something like this -

"A full Edubuntu desktop workstation that includes a gui for
creating a network server connection, so that a thin clients, ie.
computers with minimal features, can be served by my network".

>Isn't partition magic a pay program tho?

Yes, but there are others for Windows which are free (do a Google
search), and of course GPARTED for Linux, which you get with the live
versions of Ubuntu.
