Without knowing if the old HDD is IDE or sata I'll link to a cable I use a lot and write that ENCLOSURES are popular too.

I had to get a new computer because my old computer no longer has power and will not turn on. I took the hard drive out of my old computer to get all the pictures and some files off of it but I dont want to open my new machine up. Is there a way i can hook it up externally just to get those files?
