Yes, you have space for a SSD but besides having the space you need to check if you have an available SATA port on the motherboard to connect the SSD.
Your hard disk is connected to a SATA port and your optical drive is connected to another SATA port.
Also check if your PSU have an available SATA power connector. If you have a 4-pin MOLEX power cable available you could get a 4-pin MOLEX to SATA power adapter.
