Advice on what's the best office sff case (HP, Dell, Lenovo) for a gaming PC

[GhostalkerBR]

Hello friends, I wanna mod a SFF Office PC case into a gaming PC but I just want the case itself so I can install a mATX mobo, ATX 850W PSU and 2 1/2 slot RTX 3070 3 fans.

I just saw today and old HP Pavilion Slimline s5 and it seems there is plenty of room.

I'm thinking of installing the pieces as follows on the image.

I know the draws aren't proportional I just wanna show the desired layout.

But I wonder anyone here ever tried this kind of case with normal components? Any advice on other case models I could try?

I forgot to mention that I need to use a riser cable in order to make the GPU fit inside.
