There is some doubts whether a top mounted fanless psu is better then bottom. Anyway, the choice seems to be the p183 vs Factal design R3 http://www.fractal-design.com/?view=product&category=2&prod=48 It's hard to judge, not having the cases here, but to me it looks like the p183 is HUGE... Qua looks and height I prefer the R3, but I'm not sure the performance will be close to the p183. \r _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
