Swap HDD for SSD procedure

If this is in the incorrect section, please move it.

My computer is an Acer Aspire XC-780 destkop.

I want to swap the installed HDD with a SSD.

After taking off the lid I see the HDD and other than knowing how to unplug the power and data cables, I do not know how to pull the HDD out of its location.

I would appreciate step by step direction
