Counting my blessings, but I never had to replace any parts on them. They used boring SATA drives, which I had a few spares of even at the time. The bigger issues were the noise and the heat and power consumption. Not only did they take upwards of a kilowatt of power each, but being Texas I also had to take into the account the increased cost of air conditioning. I was only bitten by that one month where my power bill was like $150 more than usual, and from that point on I was vigilant about turning the servers off between uses.
