No...go away please...

Seriously? You need to raise hand, asks for permission to ask a question?  Just ask away

i think it can fit 2x360 fully internal if properly plan the loop 

not a elegant type wc style like 800d or tj07... it do fit all the accesories inside.

bought a few tools for modding...

Anyone can tell me what's the advantages of bigger radiator ?

Bigger radiator=Bigger area
However there is some case where too much radiator is overkill as the system already reach thermal equilibrium and won't get any cooler without lower ambient temperature

depends on ur heat load of your system. 

for cpu + gpu, a quad radiator is a must to maintain the water temp below 35'c.

My tri radiator got 37'c water temp for folding cpu+gpu. estimate wattage/heat of 250watt being penetrated to the tri radiator.

250watts = amount of heat = energy convert to work...

Adding more radiators/pump pressure will reduce the "delta". Thermal equilibrium is achieved when your water hits the highest temperature = Ambient + delta. If you want a lower themal equilibrium, add a ton of radiator and water flow so that your delta is smaller and keep your ambient cool. Having 5-7 120mm is more than enough to cool down 800W of heatload.

yeah, kinda agree. because of the tj-07, v2000, and now tj-11 becoming famous for wc due to separate compartment to place radiator, which isolate the heat from radiator while sucking cool air from outside.

depends ur budget..

low cost full tower
CM HAF-X
Xigmatek Elysium

mid cost
Lian Li PC-A71F
Silverstone FT-02 ( can fit 560 if modded correctly )

high cost
Silverstone TJ-07
Lian Li V2000 series
Silverstone TJ-11
and others from company like XSPC, Mountain Mod, Little Devil, Case Lab

yup unfortunately cost will be high. but hey it will be a very nice setup
