Nice little read on polycarb to polycarb bonding options...
also, I apologize to all those who don't understand the technical jargain BillA and I are throwing at each other

coefficient of linear thermal expansion (mm/m °C):
polycarbonate 0.065
Aha... here it is. Let's assume there is 20 degrees Celsius temp fluxuation inside our computer acting on our 3 inch long piece of lexan... it expands by about 0.1 millimeters. Using Polycarb's high modulus of elasticity, 0.1mm of movement will not be enough to induce or promote any sort of crack propagation.
