Hardcore's Reactor: That's One Cool Computer

"Looking for a beefy gaming rig, and don't mind getting your hands a little wet? Hardcore Computer's Reactor might just be the 100-pound computational monolith for you.

"Crafted from 2.5mm-thick aircraft aluminum and packed with powerful hardware, the Reactor is already a fairly striking and competitive machine. But there's a secret weapon sloshing around in that unassuming tank: four and a half gallons of cooling oil...."

This isn't a gimmick. Computers used for gaming tend to be overclocked, and generate heat. Lots of it. Air cooling isn't all that efficient, and liquid coolant delivered through a manifold of tubes gets complicated.

So, Hardcore Computer's Reactor has its components submerged in a bath of cooling oil.

It works, and in my opinion looks cool. But then, I'm impressed with just about anything that has clear plastic, visible circuit boards, and glowing blue lights.
