Thing is there is no room for bolts. Because of the way Dell have engineered it there's pretty much no room for anything behind as there is a plastic ABS plate that holds the power button and logo that sits flush against the back. You can see it in the pic I've attached.. I will have to be careful with the mesh not to create too much of a bump back there, and, probably dremel out the area the mesh is going into so the plastic back doesn't hit it.. It's all very fiddly sadly Edit. To give you guys an idea of the weight of this thing.. Dell quote 2.1lb or right about a kilo of alu..
Quite tired ATM so sorry if solved, but have you though of using liquid plastic to fill with?, a quick usage of duct tape or even cling film over the hole, hair dryer the film to tighten then put plate on front and pour plastic into mold, or filler if you like.
All sorted. Basically I've ordered some modelling mesh and will epoxy that to the back, then attack with Isopon from the front
