how to tell XPS from 720, 710 or 700
old XPS service tag often expired on Dell support
if you can look at motherboard DP/N, that is one sure way to tell which XPS 700 it is.
another way is to look at front panel ribbon cable
if it is 28 pin: 720
if it is 40 pin: 700 or 710.
to upgrade from 700 to 720, both front panel board and motherboard need to be changed.
case is the same. red, black, or jet black (H2C)

it is easy to tell XPS 730(X) from 720.
720 case sports X-window side panel, the silver one can fit 730/730X silver.
there is no true black 730(X).
730X side panel has a small black foam square block (about 10x10 mm) as a switch to turn off theater light when panel is closed.
720/730 side panel do not have this foam block.
