I bought a G5, but it locked up constantly, so I returned it. I had also bought 1gb (2x512 PC-3200 cl3) of extra RAM from crucial for it that I now don't need (I never installed it in the tower because of all the lock ups...I only owned it for 4 days).
It cost me $196 for both dimms, I am willing to sell them for $160 shipped (U.S.). I have no use for them now.
