Many thanks to you DJNafey for the link, just finished completing re-casing the PC but couldn't remember where all the wires went as last time I had assistance of a techie friend, but wanted to do the whole thing my self. The easy thing is to put the hardware on the MB but the wiring is another matter. I have changed my case to CoolerMaster Wave Master and got a WaveMaster 700watt UPS modular cabling which helped as you don't get connections in the case you don't want, the thing I was really flummoxed over the little 2 pin black connections but now I must have connected them all OK as the PC up and running all OK. Once again thanks for your help.
