Ok. Bboy.
1) LCD's are no longer the crap of the 90's, they can take the EMF's produced by the computer. People leave LCD's next to computers on their desks all the time with no problems, 2 inches closer is not going to do much.
2) Super cooling WILL allow you processor to reach high speeds. Its called overclocking. As the CPU remains cooler it has a better chance of remaining stable while being pushed to high speeds.
3) Computer cases come in all sizes, just becasue you like your small form factor PC doesn't mean everyone else has to.
4) Ever heard of Acrylic cases? Not all cases are metal.
5) Disco balls went out with Celerons.
6) LED's produce little to no heat so they won't effect anything.
7) Don't come in hear with 3 posts, using 2 of them to bad mouth someone else's creation. If you think this mod sucks, you need to rethink what you "know" about computer mods, because the 5 pages of people before you think its pretty freakin awesome.
Oh and props on the mod dude. I was going to do the whole LCD thing last year but didn't have the know-how or tools to do it. Also nice job making everything streamlined, looks nice.
