M14xR2 HDD + SSD in Optical Bay How To

Hello guys
I finally saved some money and I want to upgrade my lovely laptop
I already have the 750gb HDD as my primary (and only) hard disk
Now I wanted to buy an SSD and place it in the optical bay
Although
I have no idea of which SSD should I buy, How to do the process (Ive already disassembled the m14 but I dont know where and how should I place the SSD)
plus, I have no idea of which adaptor should I use
please be kind with me and guide me through this process :)
thanks :)

For the SSD
is this one ok?
Samsung 840 EVO 250GB 2.5 inch Basic SATA Solid State Drive
123£ on amazon
 
hello guys
Ive just received the 840
I know that to mount the ssd in the optic drive "zone" there needs to be an adaptor
Optibay is pretty known so I wanted to go with one of theirs
the only problem is that they do not have one for the m14
the have itfor the dell laptops
is the size the same?
