It comes with a non k edition processor so no, some people can get a slight overclock like maybe +.1ghz or .2ghz. If you didn't already buy your computer I would try to find one within the same price range with a k edition processor. I would personally recommend building one at the price for it but your choice. Lots of guides on youtube and online that could make it easy for anyone to build their own

Almost all pre-built computers have locked BIOS's which prevents the uninformed yet curious user from doing irreparable harm (overclocking has that potential). There are a few "gaming" pre-builts that allow overclocking but they are the exception - some models in Dell's Alienware line and some iBuyPower models come to mind, there may be others. As pointed out, if the computer has not yet been purchased, you could DIY (we're here to help), or look into a boutique builder such as CyberPowerPC or even iBuyPower (direct from them, they do some customization) for an overclockable PC.

If you have the computer already and feel you need some more performance out of it, first purchase an aftermarket heatsink, then look for overclocking software, there are programs that run through windows that can allow some overclocking even of non-k CPU's but as pointed out you probably won't get more than a few hundred MHz's out of it.
