I had the exact same question, go to http://www.icronticforums.com and click on the GENERAL HARDWARE forum, then click the thread titled "Best Case for Business Use" you will find some good info there.
In-Win cases are brilliant
I've been using one for 4 years and always keep it when i upgrade
They are large, built like tanks and just have eveything you need
Brilliant
Check out the Lian Li PC-60, <A HREF="http://link" target="_new"> http://www.dansdata.com/pc60.htm </A> It is a great looking case with good cooling, but doesn't come with powersupply. It is alittle on the expensive side though. They also have a full tower case and mini tower for whatever suits your needs.

You may want to look at the Antec 830sx. It comes standard with two 80mm case fans and has room for 2 more. The 830 has a 300 watt power supply, you can also step up to the 840 which has a 400 watt PSU. This case is top quality all around.
