Imaging - Rename, join to domain/OU

Hello, 

I am looking for the best way to achieve the following: 

1- Bios name is set manually

2- Machine is imaged

3- Machine name is automatically set to match the Bios name set in step 1 

4- Machine is automatically joined to the domain 

5- Machine is joined to an OU based on the naming convention

I am familiar with System Configuration tasks, but they are obviously not advanced to meet this criteria/conditions. 

Would the best way be a powershell/VBScript script that runs post-imaging?

Just wondering if somebody has some other ideas. Thank you!
