Such feats are known as emulation. A certain set of data is required (the game) and a program to run the information is needed as well (emulator). Currently the best emulator is cxbx. The homepage is here: http://www.caustik.com/cxbx/
If you read the whole website and some forums you might have learned only a few games can be played. Since Xbox 360 came out, there is little need to continue work on it, but it is open source so those who care can add to it.
Getting games is another story. You must hack your xbox and use an ftp client to download games and necessary files from the disk. Or you could do it illegally, but you can find out how do that on google since I strongly recommend you don't do that. The size of games though are huge on the hard drive.
So as you can see, the xbox emulation for the computer has brought up many problems. Continuation of it is very unlikely. So I'd say abandon hope.
Good luck with other emulations though!
