Good luck finding a similar rack; I hope you do! About a dozen years ago I saw Cathe's rack on STS and searched all over, without success. I ended up taking screenshots of the rack and then noted some modifications and had a machine shop make me one. I have custom "pockets" for loops, bands, gloves, etc. and a "secret" inside storage area so the middle area isn't wasted. It holds my kettlebell on the bottom and on the upper shelf I have a jump rope, dixie cups, discs, notebook, etc. I also have hooks for my tubes and body bar. I then got it powder coated (painted so it doesn't chip).
If you are able to do that, it may be an idea. Warning: a custom one-off item may be really expensive. But for me, it was very much worth it. In fact, I liked it so much I then made a custom barbell holder that holds a straight barbell, curved barbell, all of the plates and also my high step and extra risers. With a shelf to hold odds-n-ends (ankle weights, weight vest, yoga blocks and straps...)
