Hey Andrew! Sorry for the late reply, haven't checked the mailing list in a while.
I have a 5470 service tag # 5V2GBG2 You may see the full original config here <https://www.dell.com/support/home/en-us/product-support/servicetag/0-dHBZdFAzUVN4THRPN0NkTzFYWlNWdz090/overview> . Basically it came stock with a quad core i7-6820HQ. Sata drive with the tiny sata cable. No m.2 bracket or SSD installed to the NVME ngff slot. Nothing installed on the wwan ngff slot, and intel's wifi card installed to the ngff wireless slot. It has 3 ngff slots (M.2 NVME, WIFI, WWAN) keyed differently (Key A, B etc) and the sata data+power cable for 1 sata drive. I've upgraded ram to 2x8GB DDR4, removed the stock sata hdd and replaced it with a sata ssd. Since I needed more capacity than performance, I got a 512GB Crucial BX500. It was way more affordable than an nvme drive atm, and I didn't have the m.2 bracket either, which would mean I would only be able to secure the nvme ssd with double sided tape or other improvised solution. The BX500 is known to have an exploitable hardware encryption, so be advised to use only software encryption on that drive. That drive became my Windows 10 drive, GPT / UEFI enabled. Started using Qubes on a USB 3.0 64GB flash drive, it worked pretty well considering the constraints, but decided I needed a drive for Qubes itself. After some deep research I discovered that the WWAN slot indeed takes a SATA M.2 SSD. (source <http://forum.notebookreview.com/threads/new-latitude-5470.785426/page-9#post-10227440> ). You'd better go for the shorter ones, otherwise they'll collide with the inner plastic frame and won't fit. I believe you can fit 32 and 40mm length drives without any trouble. I couldn't find an affordable SATA M.2 with at least 256GB for Qubes (that was my personal need), so I ended up getting a regular 80mm lenght one. To make it fit, I had to "mod" the inner plastic frame, and disassemble 50% of the laptop. I opted simply to break pieces of the plastic frame in order to free space for the lengthier drive. Then, I isolated the surroundings with tape and secured the ssd (don't remember how, if I was able to bolt it in, tape it, or pressure). The SSD I used in the WWAN port is https://www.lexar.com/portfolio_page/ssd-nm100/ 256GB version You have to change BIOS settings under drive configuration to enable the required sata ports. Initialized that drive as GPT, and installed Qubes to it. You are right regarding the "dual boot". I don't have Grub. I use the "BIOS" UEFI bootmanager to choose which OS I'd like to boot. All I have to do is press F12 after powering up. I've renamed Qubes to Recovery, so it is inconspicuous. Default boot drive is the BX500 with windows. The level of compatibility of the E5470 with Qubes is outstanding. The performance is incredible. The only thing that didn't work OOB was the SD card reader, which was easily fixed by opting to kernel-latest . Docking station works 100%, with multiple monitors. Even 2 monitors + laptop monitor works perfectly. I wish it was possible to nuke Intel ME on 6th gen laptops and have it fully Opensource. It would make a great candidate for certification. My only concern right now is the decisions for the GUI of Qubes 4.1. I wonder if the separation of the GUI and dom0 would result in incompatibility with E5470 or even a big decrease in performance. This thing is perfect for Qubes if your threat model isn't government agencies high. Hope I could help, and let me know if you have further questions.
