If it's a school, I have a tough time advocating thin clients simply
because schools have a remarkable tendency to find reasons for thin
clients...especially if they're not Windows-based...to not "meet their
needs" as more shovelware comes out for Windows (like the slew of
edutainment titles written with Macromedia and compiled into EXE
format...bloated, limited, buggy and slow, but the user doesn't see
this, just the techs told to get it working).
You put in a crapload of work to get things perfectly usable just to
have it dismantled or not used within six months...
BUT to the situation you're describing. Yes, 4 gig of ram for 10 users
could easily eat all the resources. Or it may not. You only need a few
users on big flash games to make things go wonky. If everyone's doing
basic stuff...email, basic web browsing, etc...that 4 gig system could
probably handle the load, especially if you're using RAID to deal with
the I/O throughput a little better.
The only way to tell is to set up a server and slowly crank up the
clients, probably with a bootable setup to boot by network or CD, and
see what the load *your students* are putting on the server will allow
it to handle, and monitor what the bottlenecks are as they appear and
figure out how to handle them until throwing hardware at the problem
won't help you anymore. Then you'd need another server and start over again.
I've done very little with XTerms, but I have used Windows terminal
services for a school before...there are definite plusses and minuses.
