Not quite, it's 2.6" shallower and 6" taller (7" when compared to the P183).
Did everyone notice that the optical drive is on the side rather than the front? This means you can position the case sideways on your desk behind your monitor(s) and still have direct access to the optical drive, as well as having much easier access to all the back panel ports.
In this configuration it only takes up 230mm of desk depth - which if behind a monitor is probably unused anyway. Personally, I think this offset idea is the way of the future.
Alternatively, there's the little brother, the
X1000. It doesn't have the offset optical drive or the hot-swap bays, but it
adds two 2.5" mounts and shrinks the height by 1.1" and the depth by 1.7". That's just 2/3 the depth of the Corsair and makes its footprint just 59% as big!
Still heart-attack pricing though ...
