I have a PC-65B that I simply love. Mine has 2 front fans (suck), a rear fan (blow), a top fan (blow), and 2 gpu strategically places window fans (blow). Well, aside from the too many fans, I love the case... I also have a PC-70B (or 71B?) that is huge and cools as well as the 65B with only 4 fans. Both have great fit and finish, and I appreciate the well thought out layouts. The styling isn't the greatest, but that same simplicity offers mods galore.
excaliberpc.com seems to have the best Lian-Li prices lately. I think I've seen the PC-65 for around $120.
I wish Lian-li would make a case with 120mm fan(s). All of my case fans are 80 mm Panaflo L1A or speed controlled Adda. The noise is OK. But I think one or two nice 120mm fans would easilly give similar to better airflow and much less noise. Sonata is appealing, but I don't like the interior layout and functionality as well as the Lian-Li cases.
