There are so many ways of having fun with hardware. Be it servers or be it desktop components.
You can find a place for anything and if you are addicted to LN2 and pushing something far beyond its limits this is a nice place to be.
I like the dedication of KPC to the specific themes LN2 overclocking and hardmodding, so you got not tempted to spent too much time with other things around.
As long as somebody doesn't invent 48 hours day there is not enough time to test all hardware on all cooling on all voltage on all windows on all driver on...
In the end we share a lot work and knowledge together, to get the best out of our hardware for the application it runs
