nope id build it yourself. many guides on youtube to help you out
this build will perform the same or better for a lower price given you can build it yourself for free. takes a little less than 2.5hrs. 3.5 if you want cables to be very neat http://pcpartpicker.com/p/geWL
If you want to overclock, you will need to add an aftermarket cooler. A cheap one will do, provided you don't want to overclock agressively. something like a Coolermaster 212 EVO. If you are building a performance system, it is worth including an SSD, for your OS and main games. Something like a 128GB Samsung 830 is very good. Much improved performance.
