Bought a barely used Raven from a forumer here. Intel i5 with GTX1050. The mechanical keyboard is really a pleasure for touch typist. This is not an issue for me (I'm used to Kailh Blue switch that's heavy AF) but I noticed some keys have different clicky sound and different weight to others. Do note that the top row keyboard buttons are the normal membrane type. RGB keyboard is nice to have too. But the backlighting on the top row number key only backlit the symbols and not the numerals. I find this annoying.
Touchpad is good and and the surface is matte. Multi finger gesture works well.

My use case is as a desktop replacement for office works, I needed the high clocks of intel HQ series CPU. I appreciate the rear position Kensington Lock port as it keep the side of my laptop completely clear. This Raven also comes with tons of USB port (6 USB + 1 type C). 2 USB port at the back and again, keep the side of the laptop completely clear of obstruction.

If we could turn off the Red light accent on top of the keyboards, this will be a perfect business laptop.

During idle or normal office work load, the fan noise is not noticable.
Gaming wise, from my limited testing, I can say the thermals are excellent! There's two fan, and the CPU and GPU cooling are completely separate from each other. But the fans can get very loud during heavy load, but I do accept that as a price to pay for the excellent thermals. The heat exhaust to the back away from the user.

Upgrading RAM and SSD are super easy. Just 4 screws and slide out the bottom half cover, zero prying needed. I swapped the 1tb hdd to my own 480gb SSD and it's very snappy. No stupid "Warranty Void if Sticker Removed" warnings also. I guess Illegear understand this is enthusiast level laptop and trust users who will upgrade them.

Battery life is around 2.5-3.5 hours. Not Dell 7567 level but this laptop also lighter. You want to keep it plugged in anyway to keep clocks speed high.

Overall build quality is good. The design is really beautiful, pictures on the brochure doesnt do it justice. IPS Screen is decent.

The built in speakers are mediocre but usable. I do appreciate that this Raven come with separate Headphone and Mic jack, many newer laptops use combo port.

The power brick is quality stuff from FSP, power connector is also standard type which make replacement easy to find.

I just had one small issue with the left cooling fan making noise like the fan blades are hitting something but that noise is somehow gone now so all is good. I'm sure fan replacement is easy as well if required.

Between HP Omen 15, Acer Nitro 5, Lenovo Y520. Why not consider Illegear Raven? I'm very picky and critical yet I'm happy with this laptop
