Er, the first linked one's specs says that it has only two SATA connectors, when my current one has four that are all in use. Floppy I could care less about save appeasing OCD.
Of course, I might be just a total dumbass who's not understanding what's needed though, so I could still give it a shot if you're confident it'll work. Just a little paranoid over not getting it to work right after my first mistake .
