    Bit of an odd problem here, but to make my life easier, i'd like to connect one of the internal IDE ports externally.

    current setup:
    primary IDE - master - 80GB drive
    primary IDE - slave - empty
    secondary IDE - master - 160GB drive
    secondary IDE - slave - empty
    firewire/USB 2.0 port - DVD-RW+- external drive ( non-bootable :( )

    as my CD drive enclosure is non-bootable it makes installing an OS a real pain (ie 6x boot floppies to install XP for instance)

    Now in my shuttle XPC, i have absolutely no use for the parralell port, so the parralell port cutout on the back is free.
    parralell = 24 pins (if i counted right)
    IDE = 44 pins (40+ 4 power)

    how many of these pins are strictly nessesary?

    it'd only be for connecting an old CD drive that is bootable, signal quality being degraded by reduced amount of ground lines would be no problem.
    Or alternatively, are there any connectors of around 40 connectors that are a simalar size? i'm having trouble finding anything myself.

    not a huge problem, but it'd be much neater than having a IDE cable and molex connector poking out the back of the PC like it is at the moment

    Why not keep the HDDs on the same IDE channel?

    every other pin on an IDE cable is a ground wire.

    For proformance reasons.
    Deepends on cable, the 80 wire ones thats true, but the 40 wire ones are different

    IDE pinout

    Dont think you can trim that down to 25 pins :D Does the motherboard support booting from USB or is it the enclosure that wont do it?

    If u did away with a floppy drive im sure u could cram 2 hard disks and a cd-rom inside their no problem. A friend of mine has done fine and then uses a usb floppy drive if needs be.

    nope doesn't look lit you'll be able to cut it down to 25 pins :( - see IDE pinout below:

    Go to an electronics store and buy a long ribbon cable and 3 40-pin female connectors. They are quite easy to put on the cable; they come in 2 parts that pinch the cable between them onto sharpened connectors. Mount one for the motherboard, then measure how long it needs to go to get to the first hard drive. Clip the second connector on there. Get the polarity right, there is a red or striped wire on one side of the cable to show polarity. Figure out how long the cable needs to be to the third connector and put it on there. The distance between the second and third connector should be long enough to go outside the case. Between the second and third connector, cut in-between every 5th or 10th wire and pull the wires apart so you will have a bundle of lots of thinner ribbon cables. Use cable ties and braiding to clean it up and then rout the 3rd connecter out through a hole in the case. When the wire is not in use, you can bundle it up inside or behind the case. When you need to use it, plug the cd rom into the ide cable and use a Molex extension to get power to the cd drive.

    Another thing that you could try is buying 2 male 40-pin ide connectors and soldering them directly together. Cut a hole in the back of the case and glue the 2 plugs into the hole. So you have an ide plug on the inside and on the outside. Do the same with a male Molex plug. plug the 3rd connector on you current ide cable onto the inside half and when you need to use the cd drive, just get a Molex extension and short ide cable to plug in a cd drive.

    umm why not just use cable sleeving and sleve the ide (round it first) and the molex together.
