This is practically brand new. It was 1 month old when I had water damage in one of my offices and sitting on the floor, it grounded out. I sent it in to HP and they replaced everything including motherboard, processor & Power supply and gave it a fresh XP Home install. All paperwork included and it's still under warranty. Tower only. Here are the specs:

I had to run out and buy another comp the day of the water damage so I don't need this one. Good quick processor but it could use another stick of ram.
