Most, if not all, of these photo's were taken at the same time as the batch they released 10 days ago. In fact, unless Sam has only one t-shirt and one pair of shorts, it's pretty certain they are all from the same day some weeks ago.
An up-to-date photo of the completed data centre would be more reassuring.
Can you imagine the scramble if they are still working on the data centre and they go into production on the miners? Mayhem.
Uh I see him wearing more than one t-shirt. I also see a big difference between the datacentre progress and the two shirts. It's not like they hired a professional photographer for every visit, it's a few memories on a smartphone by the looks of things. Well impressed these guys pull their fingers out and are prepared to do the physical hardwork, as well as the technical and entrepreneurial. Don't see anyone else doing that. Most of you guys complained (quite rightly) for customer service in a mining manufacturer, KnC's customer service also double up as sparkies and labourers!! Nuff respect! Now where's our miners?

EDIT: Just realised there were more pics added since you posted originally Avenger.
