Have a need to ship some PC-spec servers over international freight, balance of cost and performance. Have found some short-depth rack mount cases 2U which should in theory be cost effective because of standardised CPU coolers and ATX PSUs instead of 1U/2U stuff, however there is big variance in weight of these things.

Has anyone done any collation or have any gut feel? Seems like some of the Seasonics get down to about 1.5kg.
