I can't believe that we're still including optical drives on budget builds on the edge of 2014. The optical drive is the only component included in the builds that isnt' even required. For the same reason you can imagine reasons you *must* have a card reader, monitor, OS, keyboard, mouse, web camera, speakers, thumb drive and usb powered coffee warmer, the optical drive should be left out as an optional component. Most of us either have no need for one or already have a small usb drive shared between all our computers, there is no need to include a completely optional component in the build.
For the $18 you spent on a useless component you could have gotten a 2TB drive, faster processor, better case, better MB or a pizza to eat while you built system. Even the pizza is a better deal.
