How to check compatibility between parts?

[Pole]

As soon as possible I would like to order all the parts for my first keyboard, but I am not sure about parts compatibility. I was thinking about about:
1. a plastic case from kbdfans (https://kbdfans.com/collections/60-layout-case/products/60-plastic-case?variant=36020992077)
2. dz60 aluminium plate from kbdfans (https://kbdfans.com/collections/60-layout-plate-1/products/dz60-cnc-aluminum-plate?variant=2208745685005)
3. and this gh60 pcb from aliexpress (https://it.aliexpress.com/item/32799437588.html?spm=a2g0o.productlist.0.0.867231710Szc4R&algo_pvid=7ee9f9db-ea4e-4dbf-a061-ca903690e60c&algo_expid=7ee9f9db-ea4e-4dbf-a061-ca903690e60c-4&btsid=2100bb4916070015700252743e8a9d&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_)
But I am not sure that all this parts are compatible. In their names some parts say dz60 (plate), other gh60 (pcb) and others say nothing (case). The holes between pcb, plate and case seem to be in the same spots, but can someone tell me if these parts are compatible or how can I check if these parts are compatible?
And then I have another quick question: do you think the pcb from aliexpress is good, and more in general if aliexpress is good for chep parts?
Thanks to everyone that will answer!

The case is standard Poker compatible, the PCB has holes in the right place to screw into it and the plate has holes to access the screws - this is as close to standard as you can find so it will work, if you get what's in the pictures.

The only problem is that Aliexpress PCBs are often mislabeled.  You would be very unlucky to get one without the mounting holes but finding the right firmware can be fun.
