* CPU the best at this price.
* Mobo supports front USB 3.0 ports (I have a case below to support this).
* RAM is good and has extremely LOW PROFILE, so you don't have any clearance issues, when/if you buy an aftermarket CPU HSF.
* GPU is one of the best for the $. Performs close to a 7950!
* Case has 2 x front USB 3.0 ports and is well built for the $.
* PSU is good and should last you quite some time.
