These budget systems typically won't include a lot of gamer bling like customizable RGBs and multi-zone keyboard lighting. Many will cut necessary cost corners by using a plastic chassis instead of aluminum, and you won't see sexy thin bezels like those on the MateBook Pro or Dell XPS 13. You'll also get, at minimum, 3 USB ports, an HDMI output and standard headphone jacks.
Dell Home, via its Member Purchase Program, offers its Dell 15.6" Laptop Gaming Backpack in Black/Red for $28.49 with free shipping. That's tied with our expired mention from four days ago as the lowest price we've seen for this bag. (It's the best deal we could find now by $20.) It accommodates laptops with up to 15.6" screens and features a shock-absorbent EVA molded front shield, adjustable shoulder straps, and a deployable rain cover.
