CPC would be a better bet ;-)
If the laptop has a 'stub' cable you may be able to use that, the HD will be close to the motherboard make sure it's insulated (otherwise it'll short) and has an airgap (the HD will get warm, and cause unnecessary dry joints otherwise, causing the surface mount components to fall off!). The HD mount is a metal bracket that just does this the 'proper' way ;-)
I got an extra long cable from Eyetech, but that was a long time ago!
