Intel Celeron 333
Same as this Celeron 333 but someone once removed the heatsink/fan (Shroud) solution.
My experiences with the Intel heatsink/fan are quite good. They seem to be reliable and do it's job just fine. Perhaps someone removed the stock heatsink/fan to upgrade the cooling solution with the benefit of higher clock frequencies: the Celeron 333 was quite a good choice for overclocking. Increasing the FSB to 75MHz would result in 375MHz or running it at 83MHz would boost up to 415MHz. A lot of these CPU's could run at those frequencies without problems.
