What are the important rules of replacing a motherboard?

[Diano]

My PC :
Desktop Acer Aspire T3-715, Windows 10 Home 64b. 21H1
Intel Core i5 Processor 6400
NVidia GeForce GTX745 4GB
Hard Drive : SATA3 1TB & SSD 128GB
Memory : DDR4 8GB
DVD-Super Multi drive
Card Reader
Integrated LAN 10/100/1000
Monitor : SamSung SyncMaster 933sw

I need to replace the motherboard. Have problem finding the model ID of the Acer motherboard.

This is the label on the motherboard on Acer T3-715
Which one of the letters & numbers is the model ID of this motherboard?
If none what is the model ID of the motherboard of Acer T3-715?
Or, where to find it, please?

From a search, replacement cost that acer quoted was $350+tax, which is more than the value of the pc
