This was my first one,

ran that baby in my bedroom which is in the loft/attic for just over 1 month, until the constant 35C in my room drove me to break out the toolkit and create this monstrosity,

my first and current rig... just waiting on another 5830

This was my first "high powered rig", circa August 2010

Where did you get the OpenCL-miner on August 2010?

Finally sorted my 3rd card.  It cooked the original PSU so now I use what I got.  400w for the motherboard, 350w for the 5770, and a new 850w for the 2 5830s

I like stryker wood work.

I work for Apple in Cupertino and that's how I originally got involved with Bitcoin. A friend of mine, An Apple OS Engineer is one of the earlier adopters and got me involved. I used his version until the better ones came along. Contrary to what ArtForz claims he was not the first GPU miner nor did he ever control 25% of the network.

I know personally of a three 4850 rig in May 2010.

In May 2010, the hashrate of the global Bitcoin network varied from 70 to 150 Mhash/s: http://bitcoin.sipa.be/speed-ever.png
3 x HD 4850 are capable of 225 Mhash/s with the most optimized miners as of today: https://en.bitcoin.it/wiki/Mining_hardware_comparison

So, assuming that this person he knows wrote a poorly optimized miner running at only ~2/3rd this speed, and was online only half the time throughout May 2010, he was contributing ~70 Mhash/s, which could explain the jump from 70 to 150 Mhash/s. BitcoinEXpress's claims sound plausible.
