Black plus backlight
The HP Pavilion Gaming Laptop 15.6 comes in black with three backlight "options": green everywhere, purple if you buy online and plain old white if you buy in selected (more price-sensitive) markets.
Partial hinge
That center hinge that doesn't go all the way across -- that seems to be the go-to design this year, as a way to make them look cooler.
Pavilion Gaming Display 32 HDR
The monitor that launches with the Pavilion gaming line has nice specs for the money, but the design is pure Pavilion.
Pavilion Desktop 790
The full tower model has a good number of connectors, which will come in handy if you configure it for VR or mixed reality.
Pavilion Gaming 690
The more compact desktop model still has a fair number of connections and room for storage. Both the desktop models are sleeker variants of their Pavilion Power predecessors.
Ghost white
I think that HP should offer the white-backlight model for everyone. The content creators and video streamers that HP thinks this is likely to appeal to, in addition to gamers, would probably like it more than the green or purple choices they'd otherwise have.
Ghost white back
The "cheaper" model also lacks the color-illuminated HP logo, which is nice if you have to use it for work.
Connections
On the right side are USB-C, USB 3 Type-A, HDMI and Ethernet connections.
More connections
On the other side you'll find a couple more USB Type-A connections and an SD card slot.
Profile
The laptop is relatively thin for its class.
Connections
The connectors, which include two HDMI, one DisplayPort and a couple of USB ports, seem to be easily accessible on the back.
Gaming Desktop 790
The full tower can accommodate four full-size add-in cards.
(If you're viewing this on a desktop, sorry about the awful crop.)

It can also fit four add-in cards, but only half-height.
