oh yeah i plan on using a variable 655. I've looked at those res's you linked. if they made them in a pump/res combo i would be all for it. that is why i chose the Monsoon Premium. those actually look pretty cool. if i had a different case, by different i mean more solid panes less mesh/plastic, i wouldn't mind mounting on the outside. the only place that really lends itself to be outside mounted is the top of the case. i dunno i might get a fat rad to go there actually. here are some mods people have done to the Lanboy. Lanboy ARTic Lanboy Skateboard Lanboy Air after i have looked at those. i feel the urge to go and do something crazy. >.> crap. TO THE DRAWING BOARDS BATMAN!
