Ideas on adding fans in front of Rosewill Hotswap bays?

I have two rosewill RSV-R4000s that are soon to be combined into a Unraid + DAS Combo

Right now only one unit is configured with Hotswap bays

I’m wondering if anyone has a method to add fans to the front of the chassis, in front of the hotswap bays

My main thoughts here are an abundance of cooling for heavy use drives, and I’ll be honest I want to cover the front in RGB, I have an addiction

You don’t need front fans to adequately cool your drives.

Its really just looks TBH, I have noctuas already mounted on the inside of the Rosewill hotswaps
