You do not have many choices. Silverstone
(it is a re-brand anyway) has one on the marker as does Panasonic
I am guessing you are going with a SFF system and slim drive because slot load is all but dead on normal drives. You can use an adapter to mount a slim drive in a normal 5.25 inch bay if needed.
Shop around to find the best prices since they seem to be all over the place(price wise).
Do not forget you will NEED an adapter to use those drives with normal SATA cables.
Be warned, these laptop drives are NOT as fast as the desktop drives.
