MHW has a look at the RAIDMAX Samurai XE 901 case, while heavy they feel, it is a quiet and nice looking windowed case.
"As noted earlier in the intro the Samurai's unique design comes courtesy of a molded plastic hard shelled exterior attached to a steel frame. This manufacturing method greatly reduces costs over a comparable one piece steel only design. Unfortunately, the steel skeleton means the case is heavy, weighing in at nearly 25 pounds. Though the Samurai is by no means a small case, usable internal space is reduced by several inches due to the aforementioned plastic shelled steel frame."
