Honestly, I don't know what to tell you. The only thing that comes to mind is get a Mac-Pro case and cut it up to fit your ATX board. You can find cases online from fries machines. They generally go for $4-500. Problem is they are built like $500 cases and there is a very small market for that. A market that has the money to afford a full Mac-Pro. Lian-Li had a case that looked similar in design and concept. And you can have a look at this one http://www.newegg.com/Product/Product.aspx?Item=N82E16811164061&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-RSSDailyDeals-_-na-_-na&AID=10521304&PID=3952373&SID= http://www.newegg.com/Product/Product.aspx?Item=N82E16811164... But the ATX standard isn't really designed for optimized airflow; memory is oriented in the wrong direction, CPU is positioned right behind the, flow obstructing, drivebays, and hard drives are tucked in wherever there is space left (usually the front bottom). Instead of any laminar airflow you get case makers sticking more fans along the sides, top, and bottom. Or they give up and do watercooling instead. If you have the patience, get a Mac Pro case on ebay.
