We have 7 machines doing spam and virus scanning for a number of 
client machines.  We have 2G of RAM per machine which is enough so 
things do not swap.

Why do you need so much per server to do spam/virus scanning ?  If 
anything, leave the 4G inside but just boot with i386. It will waste 
a bit, but I am guessing better than using PAE

e.g. here is one such 4G server we have.

I have never used (nor trusted) PAE.
