Fluval Fx5 vs Wet/Dry

I'm seriously thinking about replacing the wet/dry on my 300 gal with a Fluval fx5 or two. The major reasons for this is are the noise and electricity. I have the 300 in my dining room (across from a completely silent fluval filtered 150) and noise from the water and the pump is driving us crazy. Not to mention I've noticed the pepco bill is significantly larger since the wet/dry has been running.

What do you guys think? Has anyone here every used a fx5 on a drilled tank? Its an acrylic tank can't/don't want to drape the cords up over the back of the tank. Would rather just plug the overflows and use the two holes located in upper back portion of the tank. Just trying to figure out if anyone here ahs tried this.

I don't plan on using the overflows at all if I go the fx5 route. The overflows only allow me an inch of space between the water and top of the tank. I'd like to have my water level down about 4 or 5 inches below the top of the tank. the two hole drilled in back of the tank I would use to connect to the fx5. two more would need to be drilled if I added a second fx5 which may not be necessary as I'm only planning on keeping 2, 3 max fish in that tank. the holes drilled in back of the tank are connecting to my pump right now. i want to just switch them so they connect to the fx5.

i would like to use the same hose i have connected to my pump on the fx5. i already know there is a seal there and if the hose can fit the fluval, the only challenge will be connecting the intake filter inside the tank.

i don't know the model of pump off hand. i was told it was pretty quiet for a pump though. i'll check when i get home. yes, i have durso standpipes in the overflows and that has greatly decreased the waterfall i was hearing before.

red dragon? hahaha....aren't those like $600-$900? nah, i don't think so. i'll look into the others though.
