Cabinet box size

And another question. Is there any reason why I would need a 450 mm deep 6U wall mounted cabinet rather than a 300 mm 6U cabinet?
The cabinet will be for housing a 24 patch panel (cat6 or maybe cat6A), plus a 24 port network switch (they seem to be between 200 to 250 mm deep), and maybe a router.
450 mm would be a squeeze in the location it's got to go, so I'd prefer if we could use a 300 mm deep cabinet but don't know if there'd be any problems doing this.

Should be fine then.
I've not fitted patch panels or cabinets before so not sure how much space is needed

not heard of a dump panel before, but that looks neat.
I'm still temped to get the 300 mm deep cabinet. If I can't get the cables to fit in, then i will just take the door of the cabinet off. It's all going on the wall under the stairs, so hidden and out of the way.
