I want to add a new SSD to my R11. Currently have a 512GB SSD (main) with a 2TB HDD. Never thought I would need more than 512 SSD for games, but hey, here we are.

Not that familiar with this hardware. Seen a few youtubes so it seems pretty straight forward.

What I would like to know is if I add a new SSD to this rig (to have 3 main drives), I understand there is a free space to do this in the base, what do I need to be able to add it (cable wise) the drive and can I confirm that the new drive will need to be a 2.5 size?
