Can I use a Mac Pro for my office and run Parallels for my Windows-based ERP software? I have a small business that runs a Windows-based network.  I'm wondering if I can set up a Mac Pro, with virtual servers, and use Parallels for my ERP software?  Basically, can I have a Mac-based server and still run my business software?
Both Parallels or VMware Fusion will work for you.  

My personal preference is for VMware.
