Sorry for the typos I meant core p3 instead of o3 and metal side panel instead of metal dude panel

So I recently got a o3 and I honestly I’m kind of regretting it, for starters the Instructions were garbage and I literally had to drill a hole into the case because the standoff wasn’t quite fitting and now I wanted to remove the side panel to neaten my cable management and it just won’t come off what do I do, are all core p3s like this or have I got a defective unit
