I have built several of these systems, they are perfect!  Can't even hear them operating, no noticeable heat from any components, extremely power efficient.   With the 2TB HDD I am getting 30 days of recording, 20 hours per day.  
  
The systems operate on a 5 amp fuse, the car stereo draws more current.  
  
8.33 runs very fast on Windows 7, even with the little atom processor!
