Those of you who follow CES might recall Silverstone's "Mammoth" case from 2013. It was a rough prototype at the time but it hinted at a massive EATX chassis that was said to be completely dust and spill-proof, with a HEPA air filter, front and back panels designed to deflect liquid and a sealed top panel. It seemed exciting for folks who wanted a robust case that could protect systems in harsh conditions but we hadn't heard much about the Mammoth after its original showing. Seemingly extinct, we were surprised to find the case listed in a small launch headline on the company's site and even more surprised a few weeks later when we found it on our test bench. The Silverstone Mammoth MM01 has yet to go on sale so we aren't exactly sure how it will be priced, but it's suggested to cost around $300. Read the complete review.
