So I have a Thermaltake Commander MS-I and a Seagate Barracuda 3.5in Hardrive. This question is really dumb, but how do you install it? The thermaltake says I need to insert it into some drive bay but I don't have anything of that nature with the Seagate or Thermaltake. Is there something I'm missing or am I just being an idiot? If someone could help me in general with how to install it, or at least tell me who I could ask about it, I would so thankful.
