The Thon Rack 8U Live 45 is a fabulous racking flightcase for any lightweight application. It is built well and stacks well too, and its easy to attach rear rack mounting strips.
If you are wanting to use this case for amps or dimmer racks, you probably should find a stronger case. The composite or lightweight plywood this case is made from is unsuitable for heavy loads or direct attachment of castors.
Also, the paint covering, like all of Thon's case's is very high gloss and a light sanding with 160grit abrasive paper is recommended if you need to spray-paint or stencil on any logos, details etc. I found attaching a touring label plate easy.
