Jbod case recommendations

Hello,
I am looking to get a 24 hard drive JBOD case for my freenas system. I am not looking to spend lots of money on it. Just need to expand my current 3.5 inch hard drives. Any suggestions will be helpful. Thanks

To meet that requirement I would suggest eBay but right now prices are still seem a bit high probably because of people building the Chia coin systems.
