Yep I've mined about 100 BTC at least from CPU/GPU days. Of course, I do not have them today, I had power bills to pay and at that time mining to me was just something to keep my computers busy while they were running other stuff, I dont think many early miners had the foresight or true-believer-yness that bitcoin would become "something big".

My systems used to run computation tasks (BOINC projects) specifically the GPU accelerated ones. At that time I had 4x 4870x2 cards donating to those projects, and a few other random cards, meanwhile other people were solo mining BTC (which I had not heard about yet). Makes me very sad to look back and see my wallets these days, and mining maybe 0.01 BTC/day at most... soon to be 0 BTC/day.
