What contest, Jaded?
Also, I might have to look into that Dell. Seems like decent money investment for a beermoney machine. The pc im building is mainly for gaming anyways.
The one I got is an Ultra Small Form Factor which means it's slightly bigger than a personal pan pizza box. You can't put a video card in it, but you can also get bigger ones for the same price that don't have that limitation.
I also have a similar one like that I might switch to in aid of using more than two monitors. There are other ways to do it, but meh.
Get two of whatever you get then if one dies you can restore your backup to the other one and just keep going.
You might also consider buying memory. It came with 4Gb but I think 8 will be pretty optimal for mTurk + scripts + multiple browsers open. Browsers are such memory hogs.
But yeah I am not using my main machine for this, despite it having dual 27" monitors, because I don't want to disrupt everything there with more scripts, and it's nice to sit in a different space to work.
