Thank you for visiting and writing about us! You forgot to mention the coffee and cookies!
Here are some comments to your post:
We have been running beta cards for about a week now without problems, however we have had to take the setup down to do some hardware and software updates.
About the chassis: we have been working with our chassis supplier and cooling systems subcontractor. The cooling inside the chassis is set up so that the mining card coolers are constantly pushing out the hot air and the frontal fans are there only to supply fresh air. The chassis should not be a problem with overheating.
The user interface is indeed still under development, but it is almost finished (1 or 2 days left). The communication with cgminer will use the standard cgminer API connection, thus it should also work with other cgminer monitor softwares.
In other news, here are the videos:
Simulating Sampo 1T with beta cardshttps://www.youtube.com/watch?v=exvXD2K9vNADIY overview for the mining cardhttps://www.youtube.com/watch?v=Ctam5lk_xKQThank you for letting me visit, it was a pleasure, and yes I forgot to mention the coffee, cookies and the delicious ginger beer

Good to see that you have the cooling for the cases figured out, I can imagine that tunneling the air flow trough the case and the miners cooler will be sufficient to keep the case inside at acceptable operating temperatures. Now that I think of it, you mentioned just as I was leaving, that you had done some simulations for the case cooling.
And I figured that the coding part wouldn't take you long to get ready, as you seemed to have a very capable team working on the miners.
