yup, its the DealExtreme cable. I had problems with it as well, I kept getting Dirty Disc Errors when playing games from the hdd. Switching to an official cable fixed the problem. I can no longer recommend ordering the dealextreme hdd case. Just get a 20GB hdd off eBay. Even a broken one should work, as long as its not broken because the cable is damaged.
Im also now using the cable below, instead of the adapter from cpustuff:http://www.esatacables.com/detail/index.cfm?nPID=72687
you will have to break off one of the plastic tabs around the internal sata connector on this cable, but thats no biggie.

You could leave the Esata cable in the 360 HDD enclosure on cut a hole in the back. Then mount the cable facing out the back.
this is what i ultimately ended up doing. i used my dremel to cut a hole in the back of a 360 hdd enclosure that I got from dealextreme. it looks much cleaner.
