Hi Gafstu - I've got a spare 68-pin cable which looks suitable for this unit - it's yours for the postage if you want it.
It's a 6-headed 68-pin high density scsi cable - so although it would connect directly to this unit (and 5 other ones if you wanted to) you'll need a 68-pinHD--->25-pin adapter to connect it to your amiga.
By the way - it doesn't look like there's a psu with that enclosure, and £17 seems way expensive imho..
