IMO no need for a cooler if you're not going to OC. Since you aren't buying a k CPU then use the stick heatsink. I5's seem to run cool anyway.
Didn't look at costs but I suspect you can save money by getting 1600 RAM. You won't see any difference between that and the 2400 you chose. --- www.youtube.com/user/FearsomeBeaver www.twitch.tv/fearsomebeaver
