What's the BEST water case for a P4 2.4 @ 3.1 ? Can it be done?

[DivineWrath]

I'm planning on building this system soon... (as soon as some of the parts become available, that is)

Asus P4T533
P4 2.4GHz
RDRAM 1066
ATI R8500 128MB
Audigy X-Gamer
WD 120GB 7200 w/ 8MB Cache
Samsung Syncmaster 700ift
hp DVD Writer DVD200i

My question comes in 2 parts:

#1 - What is the best water-cooling case around? (Do water cases require much maintenance?)

#2 - With a topnotch water-cooling case, should it be easy to overclock my P4 2.4GHz CPU to a FSB of 133MHz ? Making it a 2.4 @ 3.1 ?

[ I figure the Asus P4T533 w/ RDRAM 1066 is already preset to run at 133MHz... ]

Let me know what you think.
