If you don't use it often and mostly access it locally, consider VMware player 
instead of server.  (You might need to install server to create new images).

If you use VM guests a lot and have access to a windows box to run the control 
console, load ESXi on the hardware and run everything as guests.

The images are fairly portable.  Just copy the directory containing the files. 
Or install something else to run them.  ESXi is an exception because you don't 
have normal access to the filesystem - but the vCenter Converter is a free 
download and will convert about anything to anything else (I think you need 
windows for that too, but it could run under an existing VM if it can see the 
image files for the others).
