I am building a Linux box from several recycled PCs and I have a choice of motherboard:

- 266MHz FSB with 512MB DDR PC2100
- 133MHz FSB with 768MB PC133

Other than that they are pretty much identical.

Any opinions?

I would go with the top one. Just looks that little bit faster even though you lose a little RAM.
 
DDR costs like 40% less than PC133 if you want to add some memory.
 
Thanks for the replies. I don't really want to add any more and couldn't if I wanted to as both RAM slots are taken up. I refuse to put any money into this project especially as the machines replacing these old PCs will be new iMacs and a mini. :D

Thanks again, I will go with the DDR board.
 
Of course you should be able to add more memory if you wanted to. The DDR board should be able to take at least 512MiB DIMMs.
