I’m thinking of buying the CORE Kit from http://www.avishowtech.com/mbhp/buy.html.
Question, can this be powered by USB?
Thanks,
Ant
Heheheh slow down there buddy 
You just posted a parts question, with a MB64 in the title, in the HUI forum… Now that’s confusing! No big problem though
As for USB power, short answer is yes, long answer is maybe… It will depend on your power requirements. If your box draws too much power, then the USB buss will not be able to keep it running.
