wrong frequency.15,750 hz Horz is standard TV frequency cga monitors use a similar frequency. EGA, VGA and SVGA much higher frequencies although it is not relevant to what he's doing.
Some shielding may be necessary mostly to make sure that there's no possible way for any high-voltage to get to the other circuits some sort of insulating material should be use under the video circuit board to separate them. Also most monitors have a electro-magnetic ring around the screen. make sure this is disconnected or at least there's no possible way for it to be accidentally or automatically engage it could erase information on the drives.
hold this helps

Jon,
I don't have an Apple, but it seems they put it all in one case! Peek
into one and see if they mount things similar to what you want!
Stay away from the BIG RED WIRE!
And keep the dust attracted by the HV out of the box! Dress the drive
cables along the chassis floor, away from the 15,750 hz Horz. osc
stuff! That's the only thing I can think of!
Good luck!
