I just took one of these out of my 1999 Gateway. LOL

The Celeron 266 is Excellent for low power settings, and is quite cheap to find on the market today.

A classic chip!

I had one of these in my first self built PC, I remember I had to disable one of the pins on the chip to get it to run at BX FSB speeds (100MHz and above) with a small piece of tape. This trick worked fantastically well and this CPU ran as fast as my BX could go - 4 x 112MHz = 448MHz, absolutely rock solid at that too.
