6061 T6 alloy 4.75mm chassis side plate notice all countersink flat head screw hole
(Stock one is 2.5mm). Include all flat head screws (24) needed for installation.

This chassis is about as cool as you can get with a chassis. It starts life as a 4.8mm slab of premium 6061 T-6 aluminum. This is then milled down to a 2.7 to 2.6 mm thickness, leaving a rib support on all main members. This gives you the strength of a thick piece, and the weight of the thinner piece.
