Evening,
You have a fun bit of hardware. Personally I would consider running a virtual ESXi or embedded cluster. You can find more information here: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2034803
With a single PC running vmware workstation or another free virtualization system you could run a whole cluster... I run a two node ESXi cluster in my basement just like this on a single machine and it's supported... no more hardware list issues.
Honestly it works the best.
Enjoy learning more about ESXi and feel free to ask questions if needed.
Thanks
