You can send your ideas to different contests, you might want to win this version too
Extra advantage is that it is open to people outside the USofA
And while we're at it, ever heard of Arduino ?
Doesn't even need Lego to build into a supercomputer
And then there is Dwengo
And BeagleBoard
here's their smallest, the BeagleBone

Installed BOINC on mine tonight.
Code:Sun 7 Apr 20:11:18 2013 | | 239 floating point MIPS (Whetstone) per CPU Sun 7 Apr 20:11:18 2013 | | 960 integer MIPS (Dhrystone) per CPU
Running Enigma@home - currently downloaded two tasks (here and here). Initial estimate was 11 hours a unit :/
We'll see how that goes - at that rate, might drop it back on Dnet, as at least that's a unit every 3 hours!
The MIPS are almost equal to an AMD K6III-450, I'll try to re-fire that old hulk of rust and install Lubuntu on it
Away on work at the minute but intending to over clock my Pi this weekend.

I currently have mine on asteroids@home with the first unit completing in 3 days 51 minutes at stock speed. If it uses around 4 watts that work unit was about 3.5 cents of electricity. Would that be hard to beat with a typical PC?
Well I'd need about 5 to match the integer speed of my Mac mini, which draws 85W at load (according to Apple, not sure on actual).
So that's maybe 20W for perhaps similar performance (if the floating point speed meant it produced the same amount of work). Downside, ARM, so it's restricted on various projects.
Overclocked the Pi using the inbuilt config file. Upped to 950MHz (High), rather than Turbo to avoid any SD card corruption that the Turbo mode could potentially add.
Benchmark for RC5 on Dnet went from 770,000 keys/s to 1 Mkey/s. Not to shabby.
Might move to BOINC at some point - what's the projects that are supported? Asteroids and Enigma? Trouble is with Enigma, it no longer has my results that it returned (no credit there either!) so I'm loathe to run that on it again.
