Yes you can, it should have the installer on the DVD

It depends on the software you want to run. If you want to run Apple Logic, Garageband or MOTU Performer, you will have to run a Mac. If you want to run Sonar or FL Studio, you will have to get a PC running Windows. If you want to run Pro Tools or Cubase, these programs are run on both platforms. The Mac will have better quality hardware and Firewire (which you will find near impossible to get on a PC). The PC will have SATA hard drive connections and HDMI output, which are unavailable on a Mac.
You can get Cubase from Steinbergs website
On the Cubase Wiki, you can find information about Cubase software features, updates, tutorials, troubleshooting tips, and user guides.

YOu forgot the important part: How do you use WHAT in Cubase
For Cubase Studio, Artist or the full Cubase program (not LE or AI), insert the USB copy protection key into the computer. Open the eLicenser Control center program that installed with Cubase. Get the license code card that came with the program and click on Enter Activation code. Type the code on the card and press continue. You will need to be online to active. The activation will then be stored on the key, allowing you to run Cubase on any computer you wish, as long as the key is inserted in that computer. For Cubase LE and AI, follow the steps in the Youtube video below under Related Links.
Cubase 5 is no longer sold or produced due to the release of the newer Cubase 6 and Cubase 7. These newer versions of the software retail for $400 each.
Yes, Audacity is free but it isn't quite as powerful. Image Line's Fruity Loops, Adobe Audition, and Cubase are just a few.
Cubase is better for the beginner. ProTools is not considered a "home" recording solutions. Try the simpler version of Cubase, Cubase Essentials.
