I'm planning to get the SSD, I just need to access the old harddrive.

Last question, I can plug a HDMI cable into the video card directly?

I can't say without a doubt it will boot though.
You can recover data off it as either a secondary drive or with a live linux disk afterwards.

and yes it supports hdmi.
