That motherboard is really cool. Never seen a mobo that comes with watercooling heatsink pre-installed.
But now looking on google I found others too, even one that includes the cpu also.
Only that price... more then I payed for my new cpu.
Looks great though, and probably great performance also.
Not sure if I need to say, but make sure the memory is compatible with the motherboard, check the QVL list before buying.
If you plan to install 4 memory modules, you must also check if those modules can work together.
Some modules only support the installation of 2, and can give troubles when you install 4 of those.
