Swap complete home cinema system for imac ?

As new toshiba xp1 projector; used for only 23hrs and pull up 80" screen for the cinema effect!  * DLP Display Technology * 2200 ANSI Lumens * 1024 x 768 Native Resolution * 2000:1 Contrast Ratio  The projector can be connected to a laptop, dvd, skybox, game box etc. The pic shows the screen both down and up and compares it to a 32" tv in the picture.  Perfect picture just like the cinema. I will demo the system before swap and expect to test the imac! The imac must also be mint and in full working condition.   ROB 07737614584
