[citation][nom]Lovecheapbuilds[/nom]You have to keep the $500 budget build to keep the builds within the economic reach of a larger percentage of your readership. However, if you would like to expand, a $750 and $1500 would be a worthy addition. It would expand flexibility, and the comparisons would be a good read.[/citation]
I'm not sure what percentage of the website's monthly income is put towards these builds, but I think 3 is more than generous. In addition to monthly builds, maybe once every Summer do a water cooled rig, as long as you can get companies to sponsor it with parts.
