A Great Machine With A Few Minor Quirks
This PC is a well constructed device, but there are a couple of minor design quirks. First, the Nvidia graphics card does block some items on the mobo, such as the battery and the second m.2 drive, however, due to the thoughtful case design, accessing the insides of the PC was very easy. I also am not impressed with the cable management -- for this price point I would expect a clean and precise design. It wasn't terrible, but I have seen better. Still, regardless of what some infuencers on social media may say, the components (case, memory, gpu, and mobo) are top notch. The glass that is used in the case is thick and luxurious. Removing it as well as the opposite side where the majority of the cabling is kept is easy with a one button release. I did find that I had to add a smidge of silicon grease at the locations where the pins for each panel secure the panel one. After doing so, the panels are installed and remove smooth as silk.. One other beef I have is with the documentation -- I think HP could have provided a bit more information. Despite what a popular social media influencer says, the cryo chamber design works really well -- CPU and GPU temps are excellent. I also had no beef with the bios options -- it is not the most comprehensive, but it does provide more than the basics. Performace of the system is what you would expect with an Ultra 9 Intel processor -- not the best, but certainly meets my needs. I haven't used the AI tools extensively, but it is nice that they are available for this model PC. Finally, regarding aesthetics, this PC as a whole is a beauty -- I love the form factor and the lighting is nicely done -- I like the Omen symbol at the top, so I leave that on all the time even when the PC is shut down.

Disappointing product, even more disappointing support
There are much better deals available. Don't buy this pc.
I did, and the graphics card failed 3 months after I got it. I am now out of the return period, so support has told me my only option is to carry this PC (which, by the way, is 50 lbs) to the nearest fedex office and wait multiple weeks for HP to repair it. This could easily be resolved with a replacement part, requiring me to carry less than 5 lbs and wait 0 days without a PC. When I pointed this out to support, they simply ended the chat on me without reply. Incredibly unprofessional.
The motherboard is also a weird custom one that doesn't seem to have a video output other than the one on the graphics card. Also, for some reason there are like 12 screws you need to undo to get the graphics card out in the first place, which is ridiculous. This is all to say - maybe you'll get lucky, and not have to interact with these problems. But why take the risk? You should buy from a company that treats its customers well when things go poorly.

Save your money build your own
This thing is trash and a waste of 4k+. The components are just awful. The proprietary motherboard sucks. You can't get a schematic for the motherboard, they say it can do gen5 and gen4 ssd's but dont tell you which slots are which and they are not marked on the board. Not to mention you have to remove the bracketed 5090 which is just ridiculous its like 10+ screws. The SSD that comes on this flagship product sucks its a 2tb wd blue...The Intel untra 285k seems just as bad as the 13900 (same cores and threads as 13/14 gen). What i mean by that is it runs hot for what seems like no reason. The only nice thing on here is the 5090 and its just that a base nvidia rtx 5090. No overclocking (of course you can do yourself) or premium parts added like aftermarket brands. Its just underwhelming. Pair it with the OMEN app (which is also one of the worst apps I've ever used) nothing feels easy on this machine. There is next to nothing special even the ram which is 5600 ddr5 is set to 4800 from them you have to overclock it if you want it to run 5600. The time I had an issue was a Saturday so of course no hp help on sat/sun just a bad experience all around. Lastly, the box is shipped via FedEx and just know that thing is going threw war before it gets to you doorstep. If you know nothing about computers and wanna play stright out the box and never upgrade anything, then this is the pc for you.

Disappointing Product
I had a very disappointing experience with this product and the exchange experience. Right after receiving the PC, the first BIOS update caused the computer to completely stop working. Also there were some other unidentifiable issues making the pc not working properly. I spent hours trying to resolve the issue, but nothing worked. For such an expensive PC, this was a huge letdown.
Overall, this has been a horrible experience, and I expected much better from HP.

Screens go black and Fans blow full throttle
When playing games my monitors will go black and the GPU fans will blow full speed. HP deemed it a graphics card error. They replaced and it just last month it started happening again, with a different GPU. I owned this PC for 12 months now and 6 of them this issue has been happening. Hands down the biggest regret purchase of my life.

Can I install Linux on this (dual boot Ubuntu or MX Linux and Windows Pro)?
Yes as long as you have a correctly formatted USB drive that has enough storage to hold the Linux programs you can go into BiOS and tell it to boot from the flash drive, refer to google to find out how to that, but it is quite easy to do.
