The problem with the Hyper 212+ has always been that it was a great $25 cooler, so availability and demand quickly skewed it into a mediocre $40-50 cooler, a price range where there were always better choices. Lately prices have been overlapping with the close-outs of the Mugen 2 (now mostly gone), which is insane, as the Hyper is not even in the same league as the Scythe.
I know, I own both. I bought my Hyper 212+ for $19.99 on sale at MicroCenter, at the same time the Egg was (briefly) gouging folks for nearly $60.
All in all, this is an excellent build, and while we may quibble with the cooler or HDD choice, it made all the right major trade-offs.
