First things first the dimensions of a 3000 Screen are
Measures: 4.09 in x 2.56 in x 0.12 in or
10.4 cm x 6.50 cm x 0.30 cm respectivly.
The Dimensions of a 1000 screen are
Measures: 4.13 in x 2.64 in x 0.16 in
10.50 cm x 6.70 cm x 0.40 cm
So as you can see the 1000 screen is a bit bigger, so if you'd ever get a 3000 screen to fit in a 1000 you'd have to do some remodelling and then yer assuming that the flexcables from the 3000 screen wil even plug-in to the 1000's ziff connectors.
But since they both have a different design, I highly doubt that you can hook a 3000 screen onto a 1000 Mobo without altering the flexcables or what not. Or am I wrong guys?
