Personally, cost prohibitive and i want as few light sources facing me when watching in a darker environment. There are a few Origin case owners here, but many come of these come with the LCD. I think I saw a recent post from someone here that was building from scratch. I think they used an LCD from another device like a portable dvd player or something.
note: the post above is my opinion. as such, when reading any recommendations from me, please do you research and seek out other recommendations and make up your own mind on your next course of action. i mean, most reasonable adults should know that, but it seems this should be stated anyways.
