Hi,
I have an opintion about the Shuttle XPC... It's a great little box, but be careful if you are a consultant and using this box with a customer.
First... check to see if your unit's power supply is available for resell or if you have to send in your XPC and have them send back a replacement. That's not cool. As it turns out only a few of their models have power supply replacement.
Second. They are really cool and quiet.
Third, they the newer models are all SATA and will not work with SME 6.0.1.
Hope this helps.
