Hi All!
Just want to show my rig.
Hope it inspire people to go big!
My goal is to fit all of these within a 15amp fuse. Basically a typical home wall socket!
Common questions
What is that?
Its called a blade. Blade are more compact and energy efficient than a traditional Rack server.
How much power does it use.
It depends on the configuration typical is 1300watts.
Mine uses off the shelf microatx board with a server PSU and low profile cpu cooler.
Where can I buy.
There are alot of places to buy 1.

My Goal continue..
So far I got it to 202 watts at idle with no fan.
110 Watts when loaded each nodes (prime95)
80 watts avg while doing BOINC.
Hurdles/Problem.
1 nodes takes 160 watts at full.
Heat, these hits 100C at full load thus throttling.
Chassis fans takes 150 watts for cooling each.
To GPU crunch or just CPU?
Noise
Diskless? Hdd use avg 5 watts
Stability from tweaks.!
Solution:
Undervolting = same performance much cooler operation.
Observation:
1333 mem to 1600 adds 5 watts from the wall.
Turbo eats alot of watts.
GPU adds heat. Downclock it. no GPU projects.
Noise will drive you crazy.
Performance and Operating cost
1 cosmo@home is ~5min per node
At 1800watts(15amp) and running only at off-peak at .08c that $52 per month.
Break even or profit? NOPE! I do boinc without grc. GRC just gave me oppurtunity to BOINC more!
