The OMEN 45L takes cooling way up, with the OMEN CRYO CHAMBER. This patented system uses the ambient air to create extreme cooling inside the system. The OMEN CRYO CHAMBER is also end user upgradable, because ice is the new fire.
The HP Brand has long been associated with quality and style, for both server and workstation classes. Traditionally big name brand case designs have lacked customization for the most part (outside of manufacturer provided upgrades). PC enthusiasts and overclockers alike have always longed for a name brand ATX case that could accept a wide array of internal components and be used as a barebones for any DIY Hardware Project.
In modern times overclocking is now embraced at the CPU and mainboard level, and HP has designed one of the coolest heavy-metal Tool-less ATX case designs for your next project build. The HP Omen 45L now on my Top 5 ATX Case List. Let's take a look at some of the high-level features.
