Question, I'm thinking of buying a Lian-Li. The PC-65 is the exact same as the PC-60, except that the PC-65 has a plexiglass window as a side panel. The PC-65 definately looks cooler with the window, but will it be noisier? Does the plexiglass absorb less sound then the aluminum? My main concern is noise, so I'd like to get the quietest one. Thanks in advance!
