I recently picked up an Acer ES1, basic laptop, and although it doesn't have an installed CD-DVD in the side where they usually are, there is a piece that looks like it could be popped off, which is where the CD-DVD would normally be, I'm assuming so they can use the same case for more expensive laptops that will have a CD-DVD installed.Is it possible to install a CD-DVD myself?Is the motherboard inside capable of have one installed?Also, how can you create a 'repair disc' if everything is usb flash?If you need more info to answer, let me know.Thanks!
