    Ever since Acer launched its affordable 15-inch GTX 1060 gaming solution, the Predator Helios 300, users around the world were immediately attracted by its excellent price/performance ratio. We also had the chance to play around with and our early verdict on the notebook is that it has some considerable drawbacks, which, by the way, aren't driven by the price tag. Acer is also planning to launch a 17-inch version of the notebook that should come as a more affordable alternative to the Predator 17 (G5-793) with GTX 1060.Interestingly, the 17-inch Helios 300 has fewer similarities with the 15-inch model than expected, aside from the design and hardware, of course.

    Pros

    • Fairly portable (thinner and lighter than the competition)
    • Decent keyboard and touchpad

    • Only one USB-A 3.0 connector

Removing the bottom plate For anything other than the HDD and RAM slots, you will have to remove the whole bottom. Remove all the screws around the bottom piece and the once located under the service lids.2. Storage One of the service lids gives access to the 2.5-inch bay, which in our case is taken by a WD Blue 1TB HDD bu[...]
