i brought one the other day to mount my SSD. tho i did have problems and ended up using the converter to install it in the floppy drive bay as my hard drive bays were none standard. anyway.
what you need to do is, go to yahoo or google and search for , 2.5 to 3.5 HDD Kit
the very first result will be for a store that is both highstreet and online so depending if u have one near u u can pick up a converter.
its basically a metal bracket that u screw the SSD into and costs £9.99
hope this helps
