Less than 3 days to pre-order the The Beast, MonsterLabo's flagship fanless case. The Beast is currently the most powerful passively-cooled chassis available, thanks to its unique design (capable of handling up to 400W TDP). It's certainly not cheap but can be reused over several generations for the next 10 or 15 years.
"The Beast is the culmination of a long process of reflection carried out at MonsterLabo over the past 3 years. Deeply rooted in MonsterLabo DNA, The Beast meets our #1 commitment: build PC cases that are the most powerful, smart and fanless possible. The Beast is an aluminum & steel ATX PC case designed and built around its two giant heat sinks."
