1. If you are installing it for the first time it is the same as normal. I made sure to unplug my other HDD though just to make sure it used the right drive. Otherwise I'm not sure how you might move it.

2. My case had a little plastic thing that you put the SSD on then you put that in. If you don't have one of those then you might have a slot that it the right size.

Like a normal HDD, If I would have a SSD I would mostlikely hide it in some litte hole.
If you have bought that case your self, there should be some adapter things so you can screw it onto either somewhere on the case or on the 3,5 inch HDD platform or what ever.

I don't have a SSD, but I think it's pretty much the same, not 100% sure tho.

1. It's recommended that you do a clean install of Windows on the SSD. You can unplug your current hard drive while doing so in case you are afraid of deleting stuff or screwing up something, and plug it in later for use as a storage drive.

2. Most SSDs should have a 2.5" to 3.5" conversion bracket included in the box. What SSD did you purchase, and was this included with some screws?

What they all said

So I should just install it on there with the HDD unplugged then plug the HDD in after im done installing OS?

I have a Kingston 120GB SSD

My case is the CM HAF 922

Not necessarily. During the windows setup it shows you which drives are available and you'll have to choose the one you'd like to install it to. Granted, you have options to remove or format entire partitions, but if you pay a little attention it's actually pretty difficult to do something wrong.

I guess it's not your first time installing windows? If not, there is nothing to fear. :)

EDIT: Even if it's your first time, just follow the instructions and you're fine.

If you've never installed an SSD before, make sure to access your BIOS before doing anything and changing the mode to AHCI. It's a SATA mode that's optimized for SSDs and required to get the most out of yours.

If you're running Windows 7, your partition is already aligned, so it doesn't matter if you do a fresh install to an SSD or if you just migrate your current install. Dozens of utilities are available for this--Acronis, clonedisk, etc. Fresh installs are definitely easier, so I'd go that route unless you just really prefer to keep your existing install.

If your case doesn't have an SSD mount, search for 'ocz ssd bracket' or 'mushkin ssd bracket' on newegg/amazon. They should be around $5.

install windows 7 to it like you always do. a new copy though, dont copy stuff from your hard drive over because it's a waste of SSD space.

you need a 2.5" bracket or mount to properly install an SSD to the case, but honestly you can just leave it hangin'. my SSD isn't mounted at all, it's just fucking sat there on top of my hard drive. it doesn't matter 'cause SSDs aren't volatile like hard drives are

I'm doing a completely new build with a brand new copy of Windows 7 Pro. I'm currently on a Mac.
