I have an Ipaq that I dropped a 1.0 ghz p3 into, but if yours are 450
mhz Celerons then they are PPGA Socket 370 and not FC-PGA Socket 370.
That means they are not upgradeable. If thats not an issue, then I'd
say $45.00 is about the right price. The MotherBoard has to have a
keyboard plugged in for the box to boot.
