For convenience, your specs can be found
here
Your case info says that there are two 3.5" bays, one will be occupied by the present HDD which should leave one for any SSD that you may purchase.
The MB specs can be found
here and show that there are six SATA 3.0 ports on the board which means that you have no worries there.
What we will need to know, what capacity SSD you wish to add + what version of Windows are you running, the computer shipped with Windows 7 but you may have upgraded to Windows 10, we need to know this as it makes a difference as to the best way to proceed, we ideally could do with you being able to keep the 1TB as is in the computer.
You are welcome btw
