If you just wanna put your working components into a new Motherboard, that should be possible. You just need a new Socket 775 Motherboard like [URL="http://www.overclockers.co.uk/showproduct.php?prodid=MB-278-AS&tool=3"]This P5Q Deluxe[/URL] for example, which looking at the [URL="http://in.asus.com/product.aspx?P_ID=esOE5RDJVEmQI86w"]P5Q Deluxe Specs[/URL]. it actually has several SATA connectors and just 1x IDE connector.
However, is your Optical CD/DVD ROM, IDE or SATA ?
Although there is a way around this in the form of IDE to SATA converters explained [URL="http://www.youtube.com/watch?v=0UtHJnMlDAY"]Here[/URL] and if needed you sould be able to pick one up for £10 or less from somewhere like Amazon.
I should add that is still a good CPU, and with a better graphics card, if you need it, you should be fine if you dont want to do a rebuild.
