I have decided just out of interest to explore ways of strengthening the span between two walls without using supports. This is especially a problem where glass tends to make the bottom of an enclosure droop from the weight.
Still a work in progress, but already i have found a way to reduce the stress however the displacement is fractionally more with chines than without. I am amiming to find a way to have no mid supports.
This is 19mm Wood with 100kg (980 Newtons) of force applied assuming the left, right and rear edges are affixed to an unmoveable fixture (ie. walls).
Red indicates intense stress although this is not outside the yeild strength of the material. Blue is good and green is well within limits. Though the one with chines has a higher peak stress point, it is more localised and not as spread out as shown in the first image.
Will update more as I progress on this and will let you all know what should be done to improve your enclosures

Well after extensive testing I can't seem to find a way to strengthen the panel (without using supports). I know some will say "why bother" but atleast now we know it is close to impossible to fix without some kind of internal support (other than using overkill material thickness). The only thing that showed promise was a way of adding lateral opposing compression to the top layer of the panel to act as a "spring" against the downward pressure of the load. But I couldn't figure out anything that would be "easy to achieve" without some specialised equipment.
If anyone else wants to test something out, let me know
