Inwin and Antec both make a wide variety of good cases at decent prices. For a really nice case, try Lian-Li or Coolermaster. My top pick would be a Lian-Li PC-60 with an Enermax Dual-Fan 465-watt power supply. You can expect to pay $145 for the case with 3 pre-installed fans on a speed switch, and $85 for the power supply. A 350-watt would be a bit cheaper if you don't plan to stack that computer full of devices.
