Looks great...now, sheathing all of the wires and being meticulous about wiring will be tedious but should be a work of art when its finished. Is it bonded with acrylic cement (the liquid type that actually melts and fuses the two pieces)? I dont think the melting temp will be of any worry to you unless something overloads...especially if you have fans installed. You could make it more water resistant by foregoing the fans and cutting holes to mount the heatsinks outside the box. Then the only places of ingess are your seams and the hinged lid. Keep the pictures coming! btw, are you a gamer by chance? This is very similar to many case mods I have seen.
