I am finally over 200k PPD. Past couple days I have cleared 200K and im adding another 2600K in the next couple weeks so then it is a for sure thing :D

The following are all my rigs in my room.

HTPC - QX6700 stock in a mATX Asus board (model escapes me) 4gb ram

Bench system - Q9650 @ 3.9GHz in a Maximus II formula LC'ed 2gb ram

Ded. Cruncher #1 - 2600K @ 4.5GHz in a Maximus IV Gene-Z 4gb ram

Ded. Cruncher #2 - 2600K @ 4.5GHz in a Maximus IV Extreme (not running yet) 16gb ram

Main rig - 2600K @ 4.8-5.0Ghz in a GA-Z68-UD5 LC'ed 16gb ram

Server - 3930K stock in a Asus P979X WS 16gb ram - I may need to sell this one

Others but still owned by myself

Parents comp - E6600 @ 3.6GHz some Asus mobo 4gb ram

Nephew's comp - E8650 stock Striker Extreme 4gb ram

I am a 27 yo that came to this hobby initially back in 07 as a means to stress my systems that I could never get stable (Striker Extreme and QX6700). Since then it has evolved into almost an obsession of finding whatever resources possible to dedicate to crunching. I don't do much in the lines of charity or community service so this is my way of contributing with something that I have a great passion for (computers).

And lately it has served as an excuse to build and try out new hardware. I just built two new crunchers with 2600K's and I plan to eventually sell them to build more with other hardware.

I'm around the 200k PPD mark. Some days below, some days above.

My fleet:

E5200 @ 2.5 GHz
X3 720 @ 3.6 GHz
i7 970 @ 3.9 GHz
X4 640 @ 3.3 GHz
E5700 @ 3.0 GHz
X6 1055T @ 3.5 GHz
i7 2500K @ 4.3 GHz
X2 4850e @ 2.5 GHz
i7 950 @ 4.0 GHz
Q9550 @ 3.4 GHz
Pentium M 770 @ 2.13 GHz
Core Duo T2600 @ 2.16 GHz

As you can see, there's a mix of old and new in there but every WU crunched is hopefully another step to better humanity!

I'm eagerly waiting to see what MM comes up with.

Also, joining the club with round about 300,000 WCG PPD. One of 4 people in my team who would qualify. My farm consists of:

1x i5 2500K @ 4GHz (Part time)
4x i7 2600K @ 4.5GHz
1x i7 2700K @ 4.6GHz
1x i7 3930K @ 4.6GHz
2x Xeon L5639 @ stock (just brought this one online)

Started off as a hobby when I was unemployed, but the more I've invested in it since I got a job, the more I've also read about people's personal reasons to do it and the papers behind the research. To sum up, it's now a hobby motivated by personal interest in the research and the potential it has.

Being part of a great team is also a big booster for motivation. Whenever I can I try to give something back :)

Thanks Not much of a nuisance, most of them I keep in a separate room, without a case, on a shelf unit. SandyBridge CPU's put out a lot less heat are a lot less power hungry than the Nehalems I used to run, so definitely a sustainable farm.

I don't have this chance yet.
