i'd go with the p182.
comes in either gunmetal or a special 'mirror' edition.
identical to the 180 except it has speed controls for the top and rear exhaust fans on the back, holes for water cooling, notches behind the motherboard tray to run wires, and an hd front panel audio connector...u might want to wait for the p190 however, as it seems to be kind of a combination of the 180 & 900. It looks like a 180, but is a little wider and a lot deeper, has a large 200mm side fan and 2 top 120mm fans. Its also designed for TWO vertically mounted psu's.
But wiring the 180 can be a b****, but with the 182 its MUCH neater, and more simple to perform. In the end its up to you to see which one has the best options. ALso if noise is a consideration at all, u may as well go with one of the p18x series...i've heard that the 900 can be loud and dusty.
I happened to get a p180b from newegg with all of the p182 features....which was a win-win situation for me; it currently lists for much lower than the 182, and i wanted black
