Hello,

Just go a g4 pegasos 2.

Question is: ram module must be only and only ddr266 pc2100 or it's possible to use an other type?
(my eyes are bliking on ddr33 pc2700 modules for cost reason)

I'm asking cause, actually, pc2100 isn't the less expensive and not the most present. At leat in my local hardware reseller.

I use two Corsair PC2700 modules with no problems. They should drop down to 2100 with no problems. Just make sure you get a good high qualiety brand and not the cheap no name stuff. RAM is one place you do not want to go discount on.
