You probably have something on your mind that does not exists.
The links given to you include all the variations possible for external Drive.
I hope that you are aware that SATA/eSata is just a matters of plugs otherwise there is No difference they both work with the on-board SATA controller.

Inside it connects to an available power supply Molex and a SATA port.
It then will provide you on the back panel SATA port and power.
From there you can take it to whatever you want without opening the case.
If you just want to connect it manually to a bare SATA Drive you will need regular SATA cable and a Molex to SATA Power cable.
