I bought a late 2005 Power mac G5 on ebay for only 120. However, the useless delivery company damaged it in transit causing very noticeable damage to the front of the case.

Luckily there was no damage done to any of the internals so I decided to do a crude job of the metal work. The aluminium casing is far stronger than you would imagine so simply bending it was not an option.
First I clamped it together at the front so the handle thing was temporarily bent into the proper shape.

Next (and don't hate me) I drilled a hole either side of the Mac just below the broken handle.

Then I put a metal rod through it and fastened it with a washer and bolt at either side before cutting off the excess.

The end result was this. It isn't as perfect as new of course
. However it is the furthest anyone has ever got in attempting to fix this kind of damage I have ever heard of, based on researching this exact issue online.

Just thought I'd share my bit of DIY repair and hope this might help anyone with the same problem
