This MacPro is perfect for storing and organizing your large photos and video files! It comes with four internal hard drives: one 2.7TB, two 1.8TBs, and one 1.4TB, for a combined total of 7.7TB of space! All drives have been formatted, and the original version of Mac OS Leopard (10.5.8) that came with the computer has been reinstalled. The tower is in good condition with no major scratches or dents. The disk drive is sometimes noisy when reading a CD or DVD, but works perfectly fine. Power cable, two OS X software discs, and all original packaging are included.
