Hi Danny,
You are welcome.
Sorry that the BP-VG4090AST is discontinued.
How many pcs do you need?
Do you already have the back plate water block BP-VG4090FE-BKP?
We will check the stock in other stores and reply to you.
Or would you like the new version BP-VG4090AST-V2.
It has good performance too.
