Almost 100%! (Also: ^helpppp)

I found a Dell Precision with very decent specs for cheap on eBay; ordered an RX580, some more RAM, a 4K monitor, and I’ve got 96% of a very fancyiMac for like 900 bucks. I feel like I'm living in the future lol

Getting Opencore up and running was largely painless after some config.plist adjustments (strangely enough, I tried Clover and never could get it going correctly...), but I have hit a brick wall with wifi and trying to get Windows booting, if anyone has any ideas:

CPU: i7 7700 GPU: Sapphire RX580 RAM: 32GB Motherboard/Laptop model: 9WH54 in a Dell Precision T3620 Audio Codec: n/a (Yeti for external USB audio) Ethernet Card: Intel on the mobo Wifi/BT Card: Fenvi T919 What guide/tool followed: OC Vanilla

What part I got an issue with: I got an issue with these two things––

A) Bluetooth works on the Fenvi, I can connect headphones, PS4 controllers, etc, however: AirDrop will show up but not send/receive; Wifi will allow hotspot connection to my iPhone, but I cannot see any networks. Card is currently in slot 3 (x4) on the mobo; slot 1 (x16 "wired as x4") is NVMe, slot 3 is covered by the friggin enormous RX580 in slot 4 (x16 gen 3). I've tried swapping the Fenvi with the NVMe adapter in 1/2, but that screwed up UEFI and didn't fix the wifi issues.

B) I had a working Win10 install on a separate internal NVMe (direct, OC/MacOS is running on a second NVMe Samsung 970 Pro via a PCIe adapter), and it still boots if I fiddle with F8-F12 before OC loads, but my shiny new monitor goes to sleep fairly quickly with no input and then takes like 45 seconds to wake up, so I would much rather be able to use OC Picker again to get in there. Problem is, that’s suddenly throwing up a BSOD “System Thread Exception Not Handled.” I’ve tried installing Bootcamp drivers, and I can eventually get to Win10 Safe Mode using OC Picker + a few restarts, if that tells anyone anything.

What files/config I am using: config.plist

Thanks! Never would have attempted this without the fine folks here.
