Did you plug in the SATA and the power cables to the SSD?

I have mind sitting in the bottom compartment in the front of my 800D where there is a cage for drives extention. Its not even connected to anything its just sitting on the floor. It really does not matter where you put it. It will fit into the hot swap bays, but I have two HDD's in there already and the other two connections are broken on mine. Plus if you have a Sata3 SSD and an old 800D without the Sata3 upgrade on the hotswap you will bottleneck the drive if you install it into the hot swap drives.

^pretty much tat Just stick it in any one of the bays. You have a crap ton to choose from. If I'm not mistaken. I believe one of them has a mounting adapter for an SSD as well.

Ah thanks, it was hidden lol. Yea everything is connected, but it doesn't seem to connect right when i put it in the bay. I have another question, what is the safest way without scratching the case to remove annoying stickers? The guy i got this PC from has some at the front wich looks horrible.
