13th Intel i5-13500 / Which components (Mainboard and RAM) for 12.0+ Hackintosh?

I'm currently on a MacPro5.1 (dual CPU with AMD RX580) and would now like to put together a new system, as the MacPro is clearly reaching its limits.

Looking to build an OpenCore Hackintosh with Monterey (Audio, Video duties) + Windows 10 (Gaming duties) on separate m.2 SSDs.

My shopping list currently consists of:

1. CPU: 13th Gen. Intel i5-13500 (Geizhals: € 259,99)

2. CPU cooler: ?

3. MoBo: ?

4. RAM: ?

5. Graphics: AMD RX6800 Founders Edition (Non-XT) (Geizhals: already purchased)

6. Case Option 1: be quiet! Silent Base 802 black, soundproof (36 dBA) (Geizhals: 160€)

7. Case Option 2: be quiet! Pure Base 600, black, soundproof (29 dBA) (Geizhals: 80€)

8. M.2 SSDs: 2x Samsung SSD 980 Pro 2TB (Geizhals: ~130€ (260€ total))

9. Power: 650W be quiet! Dark Power Pro 11 ATX 2.4 (Geizhals: Already purchased)

I'm currently still looking for the right MoBo that is easiest to configure for OpenCore.

So afaik there are Z690, Z790 and B660 chipsets compatible with the LGA 1700 series. Which determines whether you order either DDR4 or DDR5 RAM. Which chipset would you recommend? I chose the i5-13500 because it seems to be the most effective price-performance ratio for the 13th Intel generation. Is it a good choice for a Hackintosh?

General requirements for the Hackintosh:

1. + Quiet. I produce music and am very susceptible to noise :-D

(Also considerating modding the fans of the RX6800 to accomplish lower noise-floor by means of Dremel and 3x Noctua fans (like here with this fan mod of a RX580, though thats a completely different topic )

• ATX (to be able to plug in as much cards or peripherals as possible) . + No RGB Nonsense

• as many USB ports as possible **

• at least 2x M.2 SSD connectors**

• at least 2 more free PCI-E slots after the GPU (will add 1x PCI-E Firewire adapter), so ideally 3 slots.

Optional:

• 10.14 Mojave Partition

I still have a Sata III SSD with 10.14 Mojave, if you can somehow use the iGPU on the MoBo this partition could be used.

Since the RX6800 only runs using Big Sur/Monterey and above, the graphics acceleration from the RX6800 would have to be disconnected somehow in the EFI for that particular partition, so the iGPU would be used (Do not know if and how that works)

• Thunderbolt (for backward compatible Firewire adapters, to be able to spare that PCI-E Firewire card mentioned above)
