I know what you mean, you need a Slim sata 7+6 to sata connnector. You can use a normal sata data cable to connect to m/b but the power connector is smaller as it needs only 5v. If the casing you are buying comes with power supply, it may or may not have this power connector.
Anyway I can send you one if you have any problems. Just pm me yr address.

Sorry just realised this thread is quite old but the offer stands.
