Reviews for the Alienware 18 Area-51

86.2% Alienware 18 Area-51 laptop review: Performance above all else | Notebookcheck
The redesigned Alienware 18 is proof that you don't need to be the thinnest or lightest to be sexy. Its thicker profile allows for both extra performance and features not found on most other gaming laptops including CherryMX keys, multiple PCIe5 SSD slots, and an oftentimes quieter gaming experience.
