A four-pin 92mm rear fan like this is in order for case cooling. You might need cable extensions for the front panel wiring; a new power switch plus LEDs can be had on eBay for a nominal sum.
If you can live without the front USB ports, the cable extensions are unnecessary. Regarding the front audio port, it's SoundBlaster-type and has to be rewired to work with a standard motherboard. I can do it in return for reimbursement for the parts and postage.
