Your best bet would be 0U rails - something like this. They are more of small shelves on each side that the server would sit on. You can just rack that chassis to the front posts with cage nuts and let the rear hang free as that's what that design is supposed to accomplish but over the years you may see it start to droop but that also depends on the weight of everything.
Front and back are the same. If you're installing servers though you do a set like https://www.amazon.com/StarTech-com-Server-Rails-Adjustable-Mounting/dp/B083N35SCZ that span between front and back (that specific kit has support for mid verticals too).
Startech also makes universal rails, you don't need to pay for official Dell rails. $36 and they're adjustable if you ever decide to change rack lengths: https://www.amazon.com/StarTech-com-Server-Rails-Adjustable-Mounting/dp/B083N35SCZ/ref=sr_1_3?dchild=1&keywords=startech+1u+rails&qid=1613418484&sr=8-3
Just an example of a universal set, that just has a “lip” to hold anything rack mount without actually attaching to it...

You could also get universal rails or a rack shelf and just move your current PC to a rack if it fits.
Sadly those aren't available in Canadian Markets... I may just go with these instead! https://www.amazon.ca/gp/product/B083N35SCZ?psc=1
That sucks... I might end up getting something like this: https://www.amazon.com/dp/B083N35SCZ/ I've had nothing but good experiences with Startech, it's simple and gets the job done. How do you like the case though?
u/AnotherAnonGringo You mean the rails you linked ( These ) slide like the below?
they did originally but they weren't included.
I found a kit from star tech that supports up to 200lbs https://www.amazon.co.jp/gp/product/B083N35SCZ
I ordered this for my 4U server, but it might be strong enough for the disk shelf as well. Do you think this would work?
yes I will probably end up using some support, although my plan is to mount it in the lowest spot so not much lifting to do. If the rails fit sliding it in shouldn't be too hard.
Those work great for my 2u units: StarTech.com 1U Server Rack Rails with Adjustable Mounting Depth - 4 Post - EIA/ECA-310 Compliant - Supports up to 200lbs (UNIRAILS1UB) https://www.amazon.com/dp/B083N35SCZ/ref=cm_sw_r_cp_api_i_xDsmFbXPDWQ97
