I'm not sure about the cooler, apparently there is no good out of the box solution. Some people prefere the Cryorig C7 with a Noctua fan, seems to be the best combination of cooling power and noise. This is the "issue" this case has, it is so small that we just have to deal with "inferior" CPU coolers. I'm waiting for further user reports before I make my decision. Regarding PSU, it will probably be the Corsair SF600. It's more compact than the Silverstone offerings and it got some good reviews too.
It was available on caseking.de and overclockers.co.uk for a few minutes until it was sold out. Next delivery: July 2017... lol.
