I was helping a friend to do a similar thing with BC3 EQ modules but then he gave up and I sold the EQ module here on the forum. I am not sure if you have the entire strip but I had cut the EQ section out. Picture attached.
I don't think there is a specific kit for it. You just have to do the case yourself. If you do not have the means for that I could happily do it for you in 1U.
Alternatively, I have 3 slot 500 series rack and blank module metalwork. https://groupdiy.com/index.php?topic=52462.0
I have also recently designed a single slot width on board power supply for the 500 series rack. So you can make something desktop.
