Inside it I have a GTX 260 which covers a lot of the motherboard so currently I can just see 2 sata ports which both are being used for the HDD and DVD drive.
Does anyone know if this motherboard has more SATA ports and what is its motherboard?

You might be able to use a pci to sata card; check pricewatch under cards>controller. Microbarn has a 2 port card for around $17, but you may need a low profile card. Not sure how much clearance you have.
