  I have recently taken a peek inside of my A2000HD and noticed that
the 40MB Quantum drive was installed horizontally in the second 3 1/2
floppy bay.  There are four standard mounting screws that hold it in place.
I also noted that the A2091 SCSI controller has the identical four mounting
screws, and could easily contain the Quantum drive.  
  Does anyone know why Commodore does not ship the 2000HD with the drive
mounted directly on the controller card?  Also, Since I am thinking about
getting a 2nd floppy drive, can I move the Quantum drive onto the mounting
space on the controller?  If I do this will it be neccessary to low-level
format the drive, since it will now be mounted vertically instead of 
horizontally?   
  Finally while I had the machine open I performed the famous fan reversal
on my machine since I too was tired of seeing all the dust accumulate inside 
my machine.  The fan now blows air into the power supply and out of the front
of the machine.  I am thinking of adding an air filter to the back of my 
machine, has anyone done this?  Does anyone know why the fan as shipped pulls 
the air through the case to the power supply instead of the more obvious method
of blowing onto the power supply?  I would think the the most heat critical 
components in the machine would be the power supply, so one would want the 
maximum amount of fresh cool air blowing though the power supply?  Any ideas?
