BenHeck has made a new 360 laptop, this time using an Elite. Pics here: http://benheck.com/02-03-2008/xbox-360-elite-laptop#more-346
I still prefer the original: http://benheck.com/Games/Xbox360/x360_page_5.htm
Apparently if you want one of the original ones, he's said he will make you one for $10,000. If I had the money, I'd buy one.
