I've a few (not too) old HDD and instead of having several HDD casings, I thought maybe I can find some gadget like those NAS that I can shove all of them in one bigger 'casing'. Is there such a thing? I asked around shops and all they have are SATA ones. Any recommendations? My several casings are all different and I got really fed up of having to swap the power adapters everytime I need to access different HDD. Hehe.
