Yep, that's the box... :-)
The card is 10.5 inches in length which is roughly 27 cm so it should fit comfortably in pretty much any decent chassis. The cooler of the 1080 Ti features that all familiar vapor chamber cooling. On the inside you'll spot a copper vapor chamber, which is able to draw more heat off the GPU and components on the PCB including memory and VRM, ultimately allowing the GPU to run cooler and thus boost to higher clock speeds.
This vapor chamber is combined with a large, dual-slot aluminum heatsink to dissipate heat off the chip. A blower style fan then exhausts this hot air through the back of the graphics card which is exhausted at the exit to the left.

A 7+2 phase power supply is responsible for supplying the GP102 GPU with power, actually a 7-phase 2x dual-FET power design that’s capable of supplying up to 250 amps of power to the GPU. The two additional power phases are dedicated to the board’s GDDR5X memory.
You will have some extra power allowance, the reference/Founders board design supplies the GPU with 250 Watts of power at the maximum power target setting of 120%. The board uses polarized capacitors (POSCAPS) to minimize unwanted board noise, as well as molded inductors.
