OEM Hard Drive With Window
SJasperson writes "At last, you don't need to mess around with Dremel tools and Lexan (and destroy your valuable data) to get a clear window in your hard drive. Western Digital has released the Raptor X 150GB SATA hard drive. 10,000 RPM, 4.6ms seek time, 16MB buffer, and, yes, a clear window so you can see what's going on inside. Made out of a special polycarbonate lens with an ESD-dissipative coating, the lens is designed to let case modders and their groupies see the drive platters and heads without sacrificing data integrity."
Don't know if one can be constructed given the high temperatutres and pressures involed.
I think it would be way cool to film and observe in slow-motion the actual real-life view of the whole sequence of the up-stroke, fuel injection, the spark, the explosion and the resulting down-stroke of the piston and exhaust.
