Amaizing build! I especially like how you converted the HDD bays to SSD bays. From the images I see that you used ExpressCage MB742SP-B? Please correct me if I’m wrong. I don’t understans however how you managed to fix those caddys in place? How doesn’t the whle SSD cage slide in and out as you remove and insert the SSDs? Or it does but you are just careful? I want to replicate this idea in an Jonsbo N5 case and this is the only thing I don’t get about your solution.
