Since my case fans are red, I have a blue LED on my GPU, and the RAM heat spreaders reminded me of a light bar; I went with a flashing police light theme.
The "Gradually Updated Over 7 Years" build
This is the result of piecemealing upgrades together over the span of 7 years into a somewhat coherent theme. This PC originally began life with a 3rd gen i5, GTX 560, and some sweet Crucial Ballistix Tracer DDR3 LED RAM.
What remains of the original build is the case, PSU, hard drives, and a DVD player that now only reads CDs.
This build may be cursed, as I started the year off with a brand new GPU that was defective and I just replaced weeks old RAM that was also defective (both DIMMs)!
