    Nice. Digging into the 7750...

    * Removing the base cover now requires removing seven screws instead of two (like 15" has been since 7530).
    * Removing the base cover still grants access to the same stuff (two RAM slots, all four NVMe slots, WLAN and WWAN card slots). I like how three of the NVMe slots are all packed together in the corner. Indeed, there appears to be no option to install a 2.5" SATA drive in this system at all.
    * The other two RAM slots still require removing the keyboard to access.
    * Heatsink has indeed been flipped to the bottom of the system as it appeared in the video from before; you can access it immediately after removing the base cover. (Too bad you can't remove the fans individually.)
    * I also like how you can access the power adapter port without removing the palmrest.
    * Indeed, the motherboard must be removed in order to swap out the GPU card, a bit of a pain. On the plus side, you don't have to remove the palmrest in order to remove the motherboard (but you do have to remove this thing called the "inner frame").
    * Swapping out the display assembly means removing the heatsink first, I don't remember that being required before (definitely not on the M6700). Yuck.
    * The manual lists an enormous amount of prerequisites for removing the display panel, which normally can be removed by just popping off the bezel and then taking out a few screws. I can't figure out why these prerequisites are required, unless you also want to remove the display cable, but they have that component listed separately.

    This has been the case for the 7X30/7X40 too, though.

    Can someone explain the difference here? What's this SSD Door Opening?
    Bottom Cover with Smart Card and SSD Door Opening
    Included in price
    Bottom Cover with Smart Card Door Opening
    $0.00

    Also why is the first monitor $97.81 less than the second?
    First: 17.3" UHD, 3840x2160, 60Hz, Anti-Glare, Non-Touch, 100% Adobe, 500 Nits,WVA,IRCamMic/WLAN
    Second: 17.3" UHD, 3840x2160, 60Hz, Anti-Glare, Non-Touch, 100% Adobe, 500 Nits, WVA,CamMic/WWAN
    Shouldn't it be the opposite?

    Check out the service manual; apparently it's basically an extra door that allows the SSD to be removed without removing the entire bottom cover.

    yea I see it .... i'm trying to understand why it'd be useful to anyone with more than 1 m.2 ssd in the machine because if I have to send it back to the depot, I'd have to remove all of them.....still thinking whether I should get it or not...anyone have thoughts as to why just having it could be worse...any design pitfalls with this door?

    oh wait...from the link you provide...this is a secondary ssd slot or the primary??
    the pdf shows it as the primary
    I guess you can switch to anyone in the bios
    that's not the point

    Huh. The first has an IR camera (for Windows Hello face login) and the second doesn't. But the second supports WWAN and the first does not. Maybe they have a fancier display assembly to support the WWAN connection. Previously they have not allowed WWAN with a 4K display at all.

    It looks like the door allows easy access to the primary NVMe slot. Most systems will just have one SSD. There are two additional slots in the 7550 and three additional in the 7750 that you have to remove the bottom panel to access.

    I just had a chance to review the 7750 purchase page. Some things I noticed:

    - Is the RAID 5 here for all four drive bays, or just three? I know RAID was limited to 3 of the 4 NVMe bays on the Precision 7730, and just to RAID 1/0. If RAID 5 were possible with all four drives, that actually makes a fair case for populating all the NVMe bays with 1 TB or 2 TB drives. They don't need to be top of the line, with the bandwidth bottleneck situation. Of course, I would never, ever buy these drives off the Dell ordering page - for the price of one 2TB, you could populate all bays with Intel 660p 2TBs.

    - The 600 Nit display that Dell_Mano spoke of that does 2D backlighting seems to me, by far, the most powerful value proposition of the Precision 7750 and it's too bad it's not available yet. OLED-like screen performance, but on a screen that can be used non-stop for the next four years, is simply cool and not something I see in the competition yet.

    Oh, dear. Going by the aggregate, it seems clear that in most cases, Intels new CPUs are slower than their immediate predecessors, and Ryzen smokes them all. I think we all sort of knew this, but thanks for the link to the hard benchmarks.

    Bought 7750 on day 1...primarily used for working and surfing during snowbird season (or like now being stuck in snowbird locale due to covid). 4K 500 nitter (not sure if 4k is overkill cause i have bad eyesight but need the brightness), backlit keyboard, i7-10750H, intel graphics, no ssd door,: 32GB (2x16) (I didnt want to remove keyboard on new unit to replace memory), 5 year w/accidental cause I know the depot loves me, linux to save $.... held my nose at the price tag and got a cough cough discount via chat/phone call to 2900+tax plus i gotta get a 512gb samsung pro to install win10 and two sabrent or adata 2tbs or just give up and spend for the sabrent 4tb .... and all in all i think its worth it cause I need physical buttons for touchpad so that greatly limits me plus the accidental warranty from dell cause other manufactures just dont have ppl selling spare parts on ebay and I won't be burning my leg everytime I walk pass my 7+ year model dell laptop...and i might be even able to put a laptop on my lap again...a novel concept
