Of interest to me in particular...
SD chips with built-in USB adapter
Lotsa new CPU coolers
More compact liquid cooling systems (i.e., the kind meant to be mounted in a fan spot)
Various GPU and hard drive coolers
New PSUs (including more passive models, a water-cooled model, and a 300W SFF model)
More SFF systems
Take a look!
(Sorry, not sure if this goes here or Not Silent... Feel free to move it.)
