Hah didn't see your post I posted 10 minutes later.
It's pretty easy to hook up an SSD you just connect it to the motherboard and the power supply. Just look up a YouTube video on it for visuals. The SSD should come with the appropriate cables.
If you want your SSD to be your primary drive, you'll need to reformat. Basically either your SSD or your 1TB hard drive will be your boot drive. The other will be like a USB flash drive... just pure storage.
