I've just finished building my mom a computer, with all new and up to date components. So I am left with old hardware to dispose of somehow. This thing had a 2.8ghz P4 processor that still works fine, and I'd have to see it gone to waste. My dad's laptop, which he never uses, is a 5 or 6 year old Del Inspiron with a slower p4 than the 2.8. Would the 2.8 fit in his machine?
