No on the heat sinks, from what I understand that will be a big issue for many ordering just the boards. I have been searching around for sinks that would be a quick fit...but nothing really  pratical as of yet. Probably will have to be a custom made fit at best in short term, until someone specs them out and begins selling on ebay or in here?..here is a link with some insight.

EDIT: That would be something that Terrahash should add to their site as an accessory item that can be ordered....problem is, there isn't any as of yet that I can find. If i'm wrong, someone please post link to a sink.... :0
