La machine! W.P.
Me, 72 years old, so what. I love tech and have had several HP computers, monitors and various printers. All of these pieces have been excellent. This Omen is amazing. When I needed another modern device, this was a no brainer when I found it. Click, buy, no hesitation. An amazing machine! I have overclocked it and it wasn't necessary but ..... Yeah! The slowest part of this incredible machine is between the chair and the keyboard. Ya get what ya pay for ya know. If one can afford this guy, don't hesitate. I replaced the 1TB hard with a 2TB SSD drive because of all my media. also added a LG all purpose Disk drive. I am thrilled.

This is one HEAVY unit & runs cool.
6 weeks I've had my OMEN GT22-1455TX NVIDIA GeF RTX 4090 24GB GDDR6X graphics is excellent. 16GB of RAM was not enough to run MS Flight Simulator X Deluxe Gold Edition PC DVD so I added 64GB 2x32GB Vengeance RGB DDR5 DRAM XMP 3.0 what a blast. Just need 49" 3D 240Hz 0.3 8K Monitor.

Utterly blown away
Wow, what an amazing computer. I previously owned an Alienware R11 with a 3090. I would mine crypto with it and the entire room would heat up. Making it a rather unpleasant experience. Now I have this beautiful computer with a 4090. I mine crypto on it and the the computer stays quiet and cool. I'm utterly blown away, now I can mine crypto without disrupting the temperature in my office. This case is a master piece and I cant wait till they sell the case on its own so I can move my old pc components into it. Great deal, exceptional value. Happy customer. 10/10 Great Job HP

Not a perfect gaming PC but really good (especially at $3k)
I've had this PC for almost a month. It is a beast. Everything feels close to instant, and AAA games look beautiful in 4k at high frame rates. The CPU+GPU combination is very good (at least at this point in time). For playing 4k games and streaming from my PC to a handheld, this computer handles everything I need with ease. The cryo chamber seems to work well (temps stay low even with the crazy hot CPU+GPU and 4k realtime ray/path tracing). It is super easy to get into the tower and work on things. The fans are also very quiet for a PC of this size and composition. Overall, I'm very happy with this computer, especially at $3000, which is what I bought it at.
That said, it is not a perfect PC. To begin with, 16GB of RAM is low for this setup. I immediately switched out the 2x8GB DDR5 sticks with 2x32GB DDR5 sticks. That led to me discovering that the bios supports XMP (XMP lets you increase RAM speed), but setting up custom XMP profiles and getting them to work is a roll of the dice. It was difficult enough that I gave up on it and am running at the default RAM speed.
My last complaint is that Windows Modern Standby, which is the default in Windows 11, causes strange sleep behavior with this PC. This issue is probably the most common complaint for the Omen 45L (especially the power supply clicking on and off). When the PC is sleeping, the power supply will click on and off every few minutes/hour/every few hours (the period changes and I couldn't find a pattern) and occasionally turn the fans on and off. It also doesn't seem to work well with Wake on LAN. To fix these problems, you need to switch to classic S3 Sleep mode. It's a pain to switch, but it gets rid of the sleep problems the 45L has. Honestly, switching from Modern Standby to S3 Sleep should be recommended by HP for all 45L users and they should make a tutorial on how to do it. It's the most common 45L complaint I've come across by a long shot, and I guarantee some people are sending their 45L back on warranty because of this issue. It's not a PC problem. It's a Windows problem, and it can be addressed w/o the PC needing to go back to the factory.

Buyer beware
Bought this product new. Had to immediately return the product due to faulty hardware. Electrical buzz in case potentially due to the AIO fans malfunctioning. Seemed like the unit was refurbished. Now I have to wait another 2 weeks before I can even be considered to receive another unit. Very concerned about the exchange unit being similar as I have read other horror stories online around this product and faulty hardware.

Great pre-built with peculiar settings
I never thought I would go to HP to buy a pre-built, but here I am, and I'm very happy with this computer so far! I wanted to mention a few things because this information really ought to be on the specs but is omitted for some reason. Customer service wasn't privy to this information, either. The ram is Kingston 4800 MHz ddr5 (8 gb sticks x2). For some reason HP has underclocked these to run at 4400 MHz. However, after I updated the omen gaming hub software, it offered me the option to overclock to 5200 MHz. The Q&A section says it comes with 800/850 w psu, but mine came with 1200 w cooler master psu. XMP is offered through the bios, but it gives you a warning about voiding the warranty, so I didn't mess with it. You also get a warranty warning if you try to swap power modes to "extreme" in the omen gaming hub (although after last software update, it simply says go to bios - you can't change in hub anymore as of this review). There is lighting software with a lot of nice options, but it only seems to control the lights for the omen symbol and the fans. The GPU and the ram are rainbow, and I haven't figured out how to change it through the HP software. Besides these quirks, the computer ran perfectly out of the box. The packaging was interesting with the "quick release" tabs. The device arrived very quickly and came with a keyboard and mouse (unexpected!). Overall, I'm happy with this purchase!
