Note: The following applies to a lian-li pc-65 case, but you should be able to make it work for any computer
Neuroanatomist has made
this page of his lian-li with a 5" LCD. The actual LCD can be gotten
here or on ebay for about $90 now.
I plan on copying his work fairly soon.

The only drawback is that I'd lose all three of my 3.5 bays and my lian-li 65 only has 4 5.25 bays, 2 of which are occupied by a dvd and cdrw, the third a lian-li temperature display, and the fourth a zip drive. If I put in the lcd I dont have room for more expansion....but if you have a tower I say go for it.
