I use a mac pro, for everyday computing... is upgrading it to server a hassel? should i just do a mac mini with server. we have 6 sales reps small time i think a 200gb 7200 rpm mini would do the trick. want it for web server for 4 small web sites. Any thoughts on this? p.s. is the 10 client just that I can only have 10 vpn at once? or only set up 10?
