Not only can you rip out the mechanical hdd and replace with an silly smooth ssd, but also stuff it full of SO-DIMMS on the cheap from NewEgg, nnn. So when you are ordering, make sure to spec the bare minimum. Just pick an ssd with ultra low TDP for maximum battery life, like the Samsung 830/840. And too, those slow ass molasses 5400rpm hdd's make fantastic external drives with only $15 on a usb 3.0 enclosure, like the
Coolmax.
