I've just got an Antec P183. I can highly recommend it.
Very well made and if you
swap the fans then dead quiet too.
By far the best I have ever had. Mostly
metal. Hardly any plastic. Doesnt resonate. Well tought out. Very cool: i7 2600K running
at 100% for over an hour doesnt go above 55C, and that is with just one exhaust fan and
one intake fan both running at less than 500rpm.
Beats my old Fractal case
to a pulp.
If you need something bigger then the P193 is the beast.
