An Antique Jewel (Celeron 366)

I need some insight from the collected wisdom.

Via some recycling, a hand-me-down has landed on my bench -
a Celeron 366, SL36C, Malaysia, 1999, week 20.

By the grapevine, I heard this is one of the most stable overclockers around. So, my questions are: is this true? And, what would be the best MoBo to run it in? Also, is it reasonable to overclock dual processors? If so, I could try to find a mate for this SL36C?

Thanks for any good, experienced advice.

I could clarify.
The proposed Celeron 366 (possibly overclocked) system will be used for the following purposes:
Email (primary purpose, so as not to risk attacks on other high priority systems)
Browsing (Mozilla usually)
Office stuff using MSWord and/or WordPerfect
Not much else.
So, with this machine, cheap & functional will suffice, but, it is OK if it is also a bit nifty in a classical sort of way, kinda like my 1972 BMW R75/5 - runs strong, not too difficult to maintain - and, has some character.
I am exploring the notion that a dual overclocked Celeron 366 machine would be kind of similar.
If not the case - glad to hear about that too.
Thanks,
