Swapping hardware in a Linux system such as Amahi (Fedora/Ubuntu) is very forgiving and simple for the most part. Amahi does depend, however, on having the eth0 network interface and your shares depend on having the right drives and SATA ports identified between hardware changes to avoid <i>lengthy</i> repair processes. Note that all of these apply mostly the same if you're running within a virtual machine. Some VM hypervisors abstract the parts enough that Os the OS will no not notice new hardware and not rename it (eg: eth0 to eth1).
