When you say ANYTHING do you also mean the OS? If you are talking about taking it out of the box and not doing anything you have 50+GB then that should be about right. The OS plus iLife should take up about that much. iLife takes up a lot of GB's due to the Garageband loops.
The HDD should have 74.5GB available, the OS takes up about 9GB and the rest is for installed software such as iLife and any trial software installed.
If you do not need Garageband then you should do a reformat and install and only choose what you need and remove all the useless languages as they take up lots of space.
