I like being able to move the pump simply because it allows minor layout changes in the case without having to redo tubing. Moving the pump to add an additional HDD, PCI card, CC light, etc... If you have a full height server case, I guess it wouln't be much use.
The screw pump is a good way to reduce noise in my opinion. I've never heard a piston or paddle/centrifuge pump that was quiet enough.
Some people have suggested putting foam in the reservoir to mask the sound from the submersible type pumps, does that work?
