For the Peerless Assassin 120 SE, there also appears to be a V2 on Amazon. (There is also an ARGB version). Did you buy the original, the ARGB, or the V2 ?
Also, any issues with the bios after install?
Any issues with the fan connector being different that the OEM fan connector plug (such as 3pin vs 4 pin)
And, if you purchased it online, where did you purchase it from?
I am interested in buying this if a clean and easy swap out will work.
Thanks in advance.
No bios issues as all it cares about is a PWM fan header. The onboard header is 4pin, but 4pin is compatible with 3pin too. Overall it was very straightforward and easier than I expected.
A few more tips:
Confused about the note in the manual:
NOTE: The computer may ship with faster-rated memory, but its performance is restricted by the memory bus limit of 5200 MT/s.

I expect to be doing this on Monday or Tuesday, and will report back.

First, the most important part, that RTX 5080 GPU. Seeing some of the replies, there seem to be still some misunderstanding and bias about the new design and maybe some thought they are the old blower style cards Dell used to use. Dell may still use blower styles in other lines such as XPS, but for Alienware, they have adopted the standard after-market design for a while similar to HP Omen, Lenovo Legion, etc. It is a standard 3-fan, 3-slot AIB 5080 measured 12 x 5.29 x 2.17. It's custom made by MSI to perfectly fit the case especially with the side-vent design and custom SFFX PSU with supporting brackets front and back. In term of radiator dimension and fans, it sits a little above MSI VENTUS 3x but is smaller than VANGUARD and Gaming Trio, so the performance is somewhere in between too. It stays quiet and cool even oc'ed, and is significantly cooler than FE (by about 10c). I only quickly tried OC but could add 500/1800 on mine without breaking 70c with the default Performance profile. It is what you would expect from a mid-range 5080 mostly.
The CPU on the other hand, is a different story. As it is an Intel, and due to the 13th/14th fiasco, Dell has taken an extremely conservative approach in the latest BIOS updates and restrict the power and voltage of these CPUs. It has been verified by many that an i7 generally performs like an i5 and an i9 like an i7. I was hoping that with the new Aurora they may be able to relax the constraint but from my quick testing they still do the same so it won't perform to its full potential. Hope they can fix it with later updates.
There are also other changes. Chip is Z890 now instead of Z690. The standard memory speed has been reduced to 5200 but XMP is now improved to 6400. Wifi has been updated to WIFI7 (BE200) from WIFI6E, but the external antenna has been removed. 7.1 surround sound has been removed from R16 unfortunately, but 5.1 Optical remained which is sufficient for mid-range Home Theater users. There are less USB ports on the back but they added one USB4 with power.
Overall, due to the CPU and GPU combo, even that CPU is limited, it is still a very powerful 4K gaming rig and the value in the current market is fantastic especially if you can combine offers. However, it is not optimal for 100+ fps gaming mainly due to Intel CPU and further power constraint. If you want to get Ultra 9 for productivity, keep that in mind too.

Received the r16 the next day Friday.
I was shocked it was one day shipping lol!
Currently runs mh wilds on ultra with the ultra 7, 5080, 16gb ram, coming from a 1080 ti playing on the lowest settings this is amazing.
Here is the INTEL page [intel.com] for 265F and it does not mention any incompatibility. It indicates a general compatibility with 6400 MT/s memory.
[FYI I was unable to find this document title anywhere online, despite trying [intel.com]: " For additional 2DPC configuration details, refer to the Arrow Lake-S and Arrow Lake-HX Processor External Design Specification (EDS), Doc ID 729037."]
Does anyone else have any further info, or do you know where else I could look to see whether any resource lists 6400 MT/s XMP memory as being compatible or incompatible with this build (Intel 265F) ? Thanks.
IMO, its not worth too much effort or money on tweaking memory clocks with this config with 14/15th gen intel CPUs.

For gaming you can see it made little difference (4%) for an i7 under 1080p jumping from 5600 to 7200, and with a more powerful GPU like 4090. That 4% difference will be even smaller when gaming at 1440p/4K, with a less powerful GPU like 5080, and/or with a smaller jump from 5600 to 6400. That's not saying that I won't appreciate it if somebody could figure it all out, just putting things in perspective.
Strangely enough, the NVME they included is a Micron 2230 1TB. So bizarre why they would use a 2230 (which is generally more expensive) instead of a 2280.
Tested the 5080, all the ROPS are present.
The 5080 is custom built for Dell, and looks similar to to the 4090 that I pulled from an HP Omen two years ago. The case has several custom mounting brackets to prop up these cards. Instead of using a straight 12v2x6 from the power supply to the GPU, they used 3x 8 pin PCIE power cables into a 3x adapter. Shrug; probably not an ATX 3.1 PSU.
