If this will works then I can kill the last PC at the office that is not in the accounting department... There is one user not in accounting that from time to time needs to access QuickBooks, she's actually a Mac user at heart but she is stuck on an old Windows box. We have one Mac Mini (1.83 Intel Core Duo) currently unused that has 1GB of ram. The only Windows app it will need to run is QuickBooks (and that will be very rare). On the OSX side she will more then likely need to have FileMaker open at the same time, but that is it for big resource hogs. What are your thoughts/experiences, how should the performance be? Too sluggish? Usable? No problem? Long story... it has to be Parallels rather than VMWare. Adding more ram right now is not an option, but could be in the future. Can a Mac Mini have non-matching (GB) ram? Thanks for all feedback.
