The HAF 932 case can definitely fit the Cooler Master V8. A lot of people will come in to recommend better coolers than the V8, but I own it and for $55 it's a fine value and works pretty well. Running Prime 95 with an i7 920 O.C.'ed to 3.2, my temperatures don't go past 62 C. So it works fairly well. I guess it depends on how much overclocking you plan to do. I have my QPI/Uncore up to 1.3 V and DRAM up to 1.62, but if I back that off a bit (uncore), I could probably get temps slightly better.
OH, and as proof that the V8 will fit, here's a picture from Cooler Master's site:http://www.coolermaster-usa.com/product.php?product_id=2810
