Hi and Welcome!
since Samsung’s SH-S203 series drives is Sata connected, you need and external enclosure with a Sata->USB interface.
The “light” version is a plain adapter like this: (just as example) http://www.sharkoon.co.uk/html/produkte/externe_gehaeuse/drive_link/index.html
I own such an adapter, but I never tried my Sata ODD with that.
There is also another option: buy a eSata controller card (either Cardbus or Express Card - check the manual of your notebook, what of these two is supported) and connect the drive directly via Sata (eSata) to the controller card.
I have no idea, what is available in your local market, so I refuse recommending a certain product
