I have a black and a silver computer. Used to drive me nuts paying so much for the color matched components (when I can find them)..then I heard that you can paint things to match. Started with my ba4800 (now silver), then everything else. Looks awesome! Just buy a high quality spray paint in color of choice. Apply 2-3 coat, using VERY THIN layers each time or else you'll get run marks.
Hope this helps.
