Sorry for take to long, i have to go to a friend he became this as a gift from me. yes i think it is the new style case identical to this one on ebay, NO, yes and the ser. is C 001458 o06 / G80-3000LSMDE-0 /00
This would make it a 2002 vintage Czech-made board, and therefore with old-style case I'm afraid.
Observe the LED label area closely, first of all there should be a slightly recessed light grey label the width of the num block there (easier to see if the case is a bit yellowed), and LED spacing should be about 2.5 cm (1").
New-style cases do not have an extra label, rather the indicator labels are lasered on the plastic. LED spacing is about 1.4 cm, as the circuit board underneath isn't very big.
This difference usually is plainly visible on photos.
In addition, when looking at the underside of the case, old-style cases have latches on the top only, while new-style ones have them all around the circumference. Old-style cases are much easier to open.
