Hello, want to know which tools can drill holes or square like 5cm width? I wan to do it beside my psu so to route all cables behind the mobo tray. Thanks for any help.

square holes are punched, not drilled.

5cm = 50mm. depending if you want round corner radius or sharp right angle edges. you can drill 4 holes, and cut a line between them with a router or saw. for right angle, just over cut to match points. give allowances to do filing and smoothening.

if drill circle 5cm, just get a hole saw. 50mm hole saw not cheap. and have to see what material you are drilling, remember to put cutting fluid or coolant, else the teeth gets blunt easily.
