Enjoyed that video, some nice advice mixed up in with it all too - the fact that for more or less everyone, the choice of memory should be down to aesthetics and budget at any given speed as they are all virtually indistinguishable in operation would be the pick of the bunch for me.
I would take the Cosmos over the Switch I think for cases, although if price was a factor then I'd agree with your choices.
My only other change would be a 690 over the 7990 , purely because of availability, you can buy them most places, not so much the amd card.
