Rated 5 out of 5 by Icedragonkid from great if you wanna stream games does everything i wanted it to it can easily handle a duel screen set up and playing a steam game while streaming to multiple platforms. 10/10 for my wife who streams.

Rated 5 out of 5 by eating from Great PC at a great price, just stalk it. I was able to snag this with a 'corporate' discount through my workplace that compounded with an ongoing sale. It took about two months for the stars to align, but I finally pulled the trigger. If you have your eye on a 40 series prebuilt at a reasonable price, keep an eye on this until the sales drop the price to 1800, then stack a workplace discount on top of that. My final price on this including tax and free shipping was around 1720, which is a fantastic price given the components. My wife recently got a custom built Alienware that she paid more pound-for-pound, but even she said that the Omen 'looks better' and is better organized inside. The only slight drawback with this is the 16 GB RAM, but that's easy to replace if you wanted to upgrade. This is our third Omen pre-built and we haven't had any issues with them so far, fingers crossed and knock on wood.

Rated 5 out of 5 by Anonymous from 1440p BEAST This prebuilt is fantastic. My primary use is for 1440/4k gaming and easily gets over 60 fps with ultra settings and diss on. Even more fps on first person shooters. It’s quiet, looks great, keeps cool and sips power usage if you want it to. So far it’s only glitch was that it didn’t read one of the ram sticks. Once I restarted the pc it hasn’t done it again thankfully.

Rated 4 out of 5 by CastleRocketeer from Amazing fast. Well constructed. Mechanically well constructed and very solid. I tried every demanding game I could find on my 4k display including CyberPunk 2077, Doom Eternal, Crysis, and X-plane 12. I turned all the settings up to max. I didn’t achieve any fps less than 50/sec. The unigine worst case fps was > 90/fps. While doing this the Nvidia RTX 4070 got as hot as 76 C and the fans were barely on. Blender ran quickly and without hesitation. This is a VERY quiet computer. The fans only became noticeable when I started running some protein folding calculations on Boinc. The cpu ran at 100% as expected and the fans came up to full speed. Once terminated it cooled down very fast. My biggest complaint is related to storage. It only has one M.2 nvm slot. This means I have to do an image copy or full restore to increase the size of my 1TB C drive. It does have 2 sata trays but only 1 power cable.

Rated 4 out of 5 by MA-X from WYSIWYG Great machine but motherboard does not have enough upgradability except for getting a GEN 5 NVME M.2 SSD and maybe adding a 20Gbps PCI-E card.

Does this tower have a bracket/mount for an external physical Cable with Lock, to physically secure this tower to a desk? 

Asked by: Cable Lock Attachment
It has a built-in secure lock for the side panel, but not something to directly allow you to lock it to a desk. That would require a third-party lock in this case.
