Rated 5 out of 5 by from Loving it! It arrived still in tact, which was a fear of mine because I had it shipped! Everything worked great from the start. It’s very quiet which I like too!

Rated 5 out of 5 by from Satisfied Customer Definitely an amazing upgrade to my previous pc. Runs ever game and program I have like a charm, even at the highest settings. Would definitely recommend this to others looking to buy a gaming pc!

Rated 5 out of 5 by from Love it Set up is quick and easy. Everything works great. My only problem is that it didn't find my old printer and I had to download the driver software to make the connection. New computers don't have slots for all the new and old storage devices which means, for example, that I can't take the SD card out of my camera and plug it into the new HP like I do with the old HP. I also don't like having to train a new computer by getting rid of the promotional bloat ware that vendors pack with it.

Rated 5 out of 5 by from Awesome prebuilt I have had this computer for a year now and its runs great. Temps are always equalized, frames are great even for MMO's and its quiet. I have had many of my friends in the programming/coding world look into it and they say its great. If you are on a budget and want something that runs great this is the one. I will continue to run omen as long as it has the ryzen series!

Rated 5 out of 5 by from Awesome if you like gaming! It is running very close to 120 fps on Gears 5 & Halo: Infinite at 1440p with RTX 3080 GPU (& Ryzen 9 CPU) on Alienware 32-in. curved monitor... I just added a cooling fan to top panel, towards rear (3 extra fan slots available), which I'd recommend any owner adding (although I read it may void warranty).

Rated 4 out of 5 by from Beautiful, fast. I am glad I ordered it. Beautiful, quiet, fast gaming desktop with the latest Windows software. I wish it had more USB-C ports, but I can add a hub. I am a Photo/Video creative, but the specs/options available in the Omen line met my needs better than the Envy line. Delays during the build were frustrating, but now that I have it, I am so glad I ordered it. FedEx isn't the best delivery service since a signature was required, but we couldn't settle on a time when I could be home. UPS has a way to direct the package to a local store for pickup. You should consider using UPS for your deliveries since FedEx cannot do that.
