I have a full-tower case and couldn't fit the stuiff in there (to my satisfaction), so I just bought a new case (YY Cube). I've never seen a Lian Li case, but I'm not sure they're worth it if you can't fit a water cooling setup in it.
My Q500 InWin has served me well for the last five years, but I'm not emotionally attached to it so it's not a gigantic leap for me to replace it with something that will work.
