Anandtech took apart the new XBox 360 days before its release. Supposedly Microsoft made some changes to the build of the XBox so that it isn’t easily accessible by the average Joe. From reading the article it looks like it just takes a little more elbow grease than normal. This box will be hacked, I can guarantee that.
Update: Check out these screen shots of an XBox 360 being played on a Dell FP monitor.
Play your XBox 360 on your monitors through VGA inputs with this adapter, HOLY SCHNIKES!!!
