eBay, I purchased a replacement laptop fan. It was the correct dimensions but the original had a curve / notch to it. I had to take the dremmel to it to alter it to fit. It still works to this day though except it does not reach the same speed as the other OEM fan in the laptop (a replacement here in SA would have cost over R1k).
I got hit with a phishing scam once. It was well disguised and looked like it came from the client I was working for. The buggers got my CV (no personal address or ID at least).
