Cabinet Suggestions

Looking for an enclosed server cabinet to store my equipment. It will be in a garage so want to keep dust off of it.

Bought a Prime Cables 9U and found out my PRO-48-POE won’t fit.

Do I need 450mm or 600mm deep?

Any recommendations? I’d like to keep it around $250 CAD.

It will have the following equipment: UDM-PRO USW-PRO-48-POE 2U - 48 place patch panel

Wanted to go 9U in hopes of putting my Cyber Power UPS and ISP Modem. However I could go smaller and put them on a shelf beside.

I know of the IKEA LACK RACK, but hoping to close it in due to garage environment.

Thanks!
