Diesel Dan: There are a couple of mistakes with your ideas.
The BE-6 is a slot 1 board: no powerleap neos needed here, just a slocket as SoNiK said. The new Abit slocket is probably a good choice.
And despite the celeron II's inordinately high multiplier (8.5 for the 566), most have been known to move to 100MHz fsb without much trouble, often just using retail fans. So if you plop a golden orb or something on it, it should jump to 857 just fine.
SoNiK, the hd wouldn't be causing you problems generally, but when overclocking, do make sure you don't have any critical data on the hard drive because when upping the fsb, you overclock EVERYTHING, including the PCI bus, and that sometimes corrupts data on IDE hard drives.
Generally, overclocking problems are caused by either the processor itself, video cards, or in my case, my network card. Also, my dvd decoder card refuses to run 12% overclocked, so I have to stay right around the magic numbers (66 and 100MHz for BX).
Your system may allow you to go higher, even all the way up to 133MHz, and if you can do that, you'll have the fastest 133MHz platform there is, better than i820/840!
