that one was 300$ lol i cant do that, i added a new hdd and upodated it, but will all the parts fit? how do i figure that out
You have to learn the computer parts, such as, the motherboard is LGA 1155, and so is the processor, so they'll fit.
Go here: http://www.asrock.com/mb/Intel/Z77%20Extreme4/
And there's a list of supported CPUs and memory on the left side.

Also, your memory isn't under the supported list, but will most likely work anyway. To be safe, though, you should look through it and choose a kit that is on there.
