Linux server duals as desktop

[W. Wayne Liauh]

I have Corel Linux 1.2 on a dedicated AMD K6-2 machine at home which 
serves as a file/printer server and IP masquerador.  This system has 
been running continuously for more than a year now and I don't even 
notice its existence.

But since Corel Linux is not upgradable, which prevents it from 
installing the new gadgets like KDE 2.2, it's time to move to a 
different distro (either Mandrake 8.1 or Red Hat 7.2).

I don't even know whether I can set it up again.  But my first question 
is, is it a good idea to dual a server also as a desktop?  Any potential 
perils?  Thanks.
