$375 HP Pavilion 14z Sleekbook with Windows 8 - Coupon: NB3521
The machine comes with an AMD E1-1200 which is a dual core CPU that clocks in at 1.4 Ghz. Plus it comes with a relatively decent integrated GPU with the Radeon HD 7300 (you'll be able to play most pre-2009 games without an issue). But don't forget this isn't exactly a gamign rig.
For under $400, you get 4GB of RAM (most budget laptop comes in a little lower) plus 500GB of storage. The best part though is that the Pavilion 14z is not an overweight 15.6-inch beast. This 14-inch laptop is under 4 lbs and is only 1.14 inch at its thickest point. All-in-all, not a bad slim laptop to consider.
