Actually Caesar is originally pronounced kai-sar. The æ diphtong confused the English to think the c should be pronounced like an s (as opposed to k).
If you know Spanish, you will know that c before e sounds like s and c before a sounds like k. Since æ is made of ae (in that order), the pronunciation of the c should be decided from the a, not the e.
[ Now, I know that modern consensus in Latin is that c is always a k-sound, but I trust a living language more than st00pid academics.

Besides, it is known for sure that the people who actually spoke Latin didn't say c as k. ]
Here's a bonus curiosity: In Danish, Cæsar is pronounced sae-sar, but the word for emperor which is derived from Latin Cæsar is 'kejser', which is pronounced like kai-sar.

It's probably due to the same confusion as in English...
