To paraphrase esteemed literary figure Xzibit: Yo dawg, Phanteks heard you like PCs, so they put a PC in yo PC so you can game while you game. What I mean is the new Phanteks case, the Evolv X, keeps the Phanteks aesthetic the company is known for, but totally redesigns the interior of the Evolv to be roomier and more versatile.

Without increasing the size of the case compared to the older Evolv, the Evolv X made room for more cooling, more storage, and added a second mount point for a mini-ITX system at the top of the case. The Evolv X is a dual system case in the size of a mid-tower.
