Well today, after a few years of service, I retired my old Air 540 case, for one a bit smaller since space is a bit limited on my new desk… I went out and bought an Enermax Equilence (https://www.frys.com/product/9359470?site=sr:SEARCH:MAIN_RSLT_PG) and I really like it so far. We shall see if it’s as good to me as my air 540 was.
