You can search here at Anandtech for reviews of the In-Win BUC and the Fractal Design Arc Midi. I think the BUC gets better numbers for cooling, but not by a whole heckuva lot. I went with the Fractal Design Arc Midi and loved working with it. It's just a well put together case. I'm perfectly happy with my airflow/temps. I added several 140mm case fans, something that is very inexpensive, though that would probably bring the price slightly above $100. I haven't checked prices recently, but both cases were selling in the sub-$100 range when they were reviewed here. Oh, one more thing about the Fractal Design Arc Midi -- it's just a tad wider than many mid-tower cases so it is a little easier to fit in some of those monster air coolers. I had enough room for a Hyper 212+ and a side case fan. Many other cases would permit the 212+ with no problem, but likely not also a 140mm case fan.
