Gigabyte Project Stealth DIY SKU:550079

Either the 12900K or the 13900k would be the fastest processors for that chipset.

Any of the Intel processors can be air cooled, you'd just spend more for a good cooler for the higher end processors.

For WiFi, I would probably go with ASUS AX1800 PCIe WiFi Adapter for $39.99

For PSU, at least a 750w, I tend to prefer Gold rated ones....

The Ram should be ok with any Intel XMP ram, just depends on your preferred speeds.

The SSD, you can't really go wrong with a 980 or 990 Pro 2TB

Let me know if this helps!!
