I recently rebuilt my home PC up to a multi-processor Celeron system, it's running quite happily at Dual 747Mhz, as I'm writing this actually...

I was requested to "write up" my experience by a few friends and had the article featured on a hardware magazine, I thought I'd share it with anyone who reads the digital photography review and may be interested, you can find it at:

Dual Celerons - Journal by Phil Askey

(Fear not I'm not venturing into PC hardware, this was a one off.)
