She's a bit tweeked. New chassis is a given. I was hoping to NOT have to replace all 4 chassis' on these 4 pro700's due to the rarity of them.
My chassis wasn't quite that bad. The transformer was against the heatsink like yours, but the covers were still mostly straight and flat. I made a lever press out of wood scraps and slowly worked the chassis straight by pressing down on the high chassis bends with the chassis strategically supported on wood blocks. That got the back straight, then used a adjustable crescent wrench to slowly get the waves out of the flange where the cover screws thread.
Both covers had a slight bend by that rear center screw, slow gentle tapping with a ball pean with cover on a wood block got them straight.
Same with the transformer bell.
In the 700 Pro thread I show repositioning a chassis cover screw to strengthen the chassis, keeping it away from the backplane, and filling and staking the old threaded hole.
Sunday or Monday I'll post a photo of the press I made. Just a few pieces of scrap wood. Those chassis and plates are unique and worth saving.
