Thinking of fitting a case fan at rear but unsure iof connections I don't appear to have any on the mother board least nothing like imageds I've seen have a couple of spares from the PSu one very large with several cables and one smaller with 4. Also what looks Like an extension one spare tee'd of my dvd writer. Anyone any idea which I could use and therefore which fan would be suitable Thanks

Get one of these and you will find there is an adaptor in the box that allows you to connect the fan to one of the available 4 pin power connectors in your case. Juist means that the fan is on all the time there is power and you can't control speed. They are quiet fans though.

Thanks my problem is not sure what I can connect to or is any 4-pin socket ok to use Normally I'd never go inside the box but reluctant to pay to fit something that only cost a couple of quid

You should find a spare four pin socket, but even if there isn't the connector in the box allows you to connect the fan using a splitter provided. This means you can use any four-pin power connector that is already used by another device. Just make sure that the cables do not interfer with any fans.

Fitting the fan is straight forward, screws are provided. Most likely your case already has two holes you can use. Just make sure that you position the fan to extract the air, by ensuring that the arrow on the fan body is shown pointing out of the PC case.

Here you go, a handy article (with picture) about Molex (IE. 12v) connectors. They should be the same as already connected to your optical drives and maybe (assuming they are not sata) your hard drive/s.

Yes when you take off the cover you will see that the four-pin connectors are all the same.
