I would consider myself a Case Ricer...... Here's what I've done to my case so far:
Dynamat Extreme on all inside panels, Cut holes in dynamat where screws protrude.
Modded case fan holes, added 120mm intake Toyo fan by enlarging an 80mm hole
Wrapped all wires with yellow electric tape in spiral pattern
Neatly routed cables with yellow split loom and terminated ends with black electric tape
Painted case with 4 coats of glossy black laquer with 2 coats of clear coat for a mirror finish.
Added external Chrome knob to control a variable resistor (rheostat) to manually control Fan rpm.
Added mercury temperature gauge to monitor ambient temperatures and graphics card
Mounted full sized thermal take golden orb on Geforce which takes up 3 pci slots that I don't use
Used thermal epoxy to mount heatsinks on hot spots of my motherboard after viewing it through thermal imaging
Bound external wires with Yellow split loom
Painted Edges of fan tips white to produce a white Ring while they spin
Put stickers such as Pirelli, Powered by Honda, and Sony Mobile on my components. (Small scale stickers from 1:10 scale
HPI bodies)
Put stickers on keyboard since I never have to look at keys anymore. I might paint the keys.. (And use a photo of the keyboard if I ever need a reference, hehe)
Have presentable wire diagram of how my hardware is hooked to my motherboard.
Currently have no lights (got purple neons, and red strobe lights, but I think they looked plain useless and inneffective.
Since my photoservice bombed I will have to find a way to post digital pics... I might have a descriptive angelfire site up when I have the time.
