OpenCore for Optiplex 3050 SFF - a lower powered version Kaby Lake processor. This machine is so quiet, I can't hear the fan running. The PCIe M.2 SSD works flawlessly at x4. Plenty of performance for a server that stays on all the time. This is a computer that has no comparable Apple product, so no SIMBIOS is a perfect match. Fortunately, WhateverGreen and Lilu handle everything. Strangely, the 'About this Mac' reports a Core i7 processor. Probably something to fix within ACPI, but it's purely cosmetic.
CPU: I3-7100T with HD630 integrated graphics (Intel Iris Plus Graphics 655 - Mobile!), ALC3234 audio, Realtek RTL8111HSD-CG GigEth, USB3.1, USB2 front panel, USB3.1, USB2 rear panel, HDMI, DisplayPort, PCIe M.2 SSD, Bios 1.22.1 - latest as of 2022-10-17
OS: Sonoma 14.7 (likely the upgrade to Sequoia would be successful, but since this is my daily use machine, I'm waiting until early 2025 to give it a go)
OpenCore: 1.0.1
SMBIOS: iMac 19,1
SMBIOS that does not work: Macmini8,1

What's working - everything necessary to make this a stable mac-mini like computer
- ethernet
- audio
- Sleep/wake - Magically, this started working in a recent OpenCore update.
- dual monitors (1920x1080) both HDMI; one attaches to the 3050's HDMI port and the other HDMI cable through an adapter to DisplayPort.
- Messages - just works as expected
- USB - full USB3 speeds off all the ports
What hasn't been tested?
- Wifi and bluetooth - my computer was barebones, not including a drive or wireless card. Since I operate with hardwire ethernet, no need to test wireless. I would expect the same challenges as with other non-Apple wifi cards.
- Airdrop - no bluetooth or wifi
- Microphone - others have mentioned this is a challenge. I don't need a microphone, so I disabled it in the BIOS. I use a USB webcam with mic, which just works.
