Most of them look like the above, what does it plug into? whydoes it have soo many gold pins at the bottom?

Sorry on the slow reply!!

I read somewhere that there were 3.5in motherboards and stuff, is that just a farce? If not, that would rock.

And the ones with the pines, which plug into a motherboard then, can they be used on their own?
