I have mine now, detailed measurements of the inside: minimums are 710 x 510 x 300. The case has a slight taper so the top dimensions are a little bigger at 720 & 530 , if you ignore the screw bosses in the lid and wheel/handle pockets you have 320mm deep.
Actual outer dimensions are 790 x 600 x 360, proving Chinese mm are slightly different to Australian ones, probably why they build the bums the wrong shape in chinese trousers ...
There's not much in the bottom that intrudes (see photo), the bottom of the case is also nicely reinforced.
Not all the foam is pluck there are a total of 5 pieces, one 40mm solid, one 80mm solid, 2 x 80 mm pluck and a 40mm waffle.
The extendable trolley handle is a little on the flexy side (see photo), not sure how durable that piece will be.
The lid is a little flexible but has screw bosses (see photo) that could be used to add some ply for additional strenth if desired. Stands up vertically nicely, a space saver in my application.
Weight is listed on the carton as 18KG.
Latches are plentiful and seem solid, I'm a happy camper!!
