My PC isn't eligible for the Windows 11 upgrade

I'm trying to figure out why a PC that I built for my parents a couple of years ago isn't compatible for Windows 11 upgrade. I have the specifications below:

CPU: Intel Core i3-10100 3.6 GHz Quad-Core Processor 

Motherboard: Gigabyte B460 AORUS PRO AC ATX LGA1200 Motherboard

Memory: Corsair Vengeance LPX 16 GB (2 x 8 GB) DDR4-2666 CL16 Memory 

Storage: Kingston A2000 250 GB M.2-2280 PCIe 3.0 X4 NVME Solid State Drive

Storage: Samsung 860 Evo 1 TB 2.5" Solid State Drive

Video Card: Gigabyte WINDFORCE Radeon R9 270 2 GB Video Card

Case: Corsair Carbide Series 200R ATX Mid Tower Case

Power Supply: EVGA 600 BQ 600 W 80+ Bronze Certified Semi-modular ATX Power Supply 

Optical Drive: LG WH14NS40 Blu-Ray/DVD/CD Writer

Operating System: Microsoft Windows 10 Home OEM - DVD 64-bit

I checked the requirements list for Windows 11 and it seems like all of the parts are compatible. What am I missing?

Thank you
