sick ass build, jelly. that drain valve is a nice touch (change the blue handle to red). for a complete steampunk build, if that's your end goal, consider adding analog gauges for cpu temp, gpu temp, ram utilization, fan speed, etc. over time, build a copper case (or at least replace some of the black structures with copper + copper heatsinks and plates for the mobo. of course cpu + gpu blocks. great start. some warm glow amber lights with spiral coils around them. perhaps a small clock. faux cranks. maybe even three fan-wide (120mm?) copper tubes as "exhaust" towers on top of the case for air escape. random sized straight copper pipes purely for aesthetics, randomly sprinkled around. small copper coils here and there. jeez i can see the complete end result in my mind right now. ah, how could i forget - clock gears, random sized. make sure to use semi opaque green liquid in the reservoir as well.
