Just me that reaches for a 2mm drill then? I realise people may react in horror at this, but your chances of getting swarf in the PSU are slim to negative. Oh and while you’re in there, please remove the 0.47uF RIFA before it explodes, assuming it hasn’t already of course in which case it’d be best to clean up the mess it left when it did.

All the other supplies I've messed with just had screws along the bottom. Trying to remove the bottom of the casing so I can work on the supply itself. Link to a pic of it.
