In my opinion, stock cooling is sufficient these days unless you're doing heavy overclocking or have other needs (passive cooling for noise reduction, for instance) but those subjects are beyond the scope of this guide. Not when that was written. Go read launch reviews. I'll change the text to reflect the current state of things, thanks. Because even with a 256GB SSD, many people would still be forced to have things like games on a secondary drive. I don't even have half of my games installed and they occupy about 500GB. The power and noise differences between WD Green and Black drives are beyond negligible in this type of system. Yep, for $17 it seems worthwhile to list a secondary optical drive for the slight bit of added functionality. The whole point of our guide is to offer a complete blueprint for each budget that works fine as is, but can be easily tweaked to your needs. If you barely use optical drives, obviously you'd leave one or both of them out and that's totally fine. Thanks for the recommendations.
