I have this exact config at home :) Only difference would be the raid type and 
controller I am sure, I used a pretty high end LSI SAS Card with sata's hung 
off it. I would seriously recommend LVM, its so flexible, and I would take that 
raid 5 and replace it with mirrors personally, but you are using it at home I 
guess. Most people forget to factor in the downside to raid 5: Slow regens that 
kill performance while being non redundant during the only one possible failure 
it could have.

Godo luck!

But is there really a performance difference between LVM & file based VM's?
