I have a 105 gallon tank - if I put the Fluval 405 filters in the cabinet
under the tank, the canister base will be about 4' 10" below the water
level - the instructions say that the base must never be more than 4' 5"
below the water level - the hoses are long enough - is there going to be a
problem with the 4' 10" distance?

The extra height produces more head pressure. Your filter will pump
somewhat below the rated waterflow. If you can, put it on blocks or a
shelf to bring it closer to 4'.
