Hard drive bay

[aeona]

Hi, just a small question, bit a of a newbie when it comes to hard drive mounting so...

I have an NZXT M59, I used some hard drive rails that came with it to put 1 HDD in there but now I'm wanting more than one.
Now, I don't know what bracket or rail or whatever to put in there to put more hard drives in there( 3.5", 2.5"? there's so many). Total newbie question but it'd be greatly appreciated if I'm pointed in the right direction!

Thanks!

A 3.5 inch drive with some of the extra rails that came with the case would work fine.
