Thought it was going well, then decided to trial fit the GTN750... fits great, as long as it isnt connected to anything!. Forgot tht the connector block and cooling fan unit stick out 2" beyond the back of the rack! Where Ive put them, there isnt room because of the fron cross brace... Panel thrown away and I have to start again. Cut a new piece using the old one as a template, then started to figure out how to get it all to fit yet again. Eventually found a way to get it to fit (hopefully) Started cuttin the holes again for the main bits...
