i have a couple questions about fans first i have a bunch of old computers can i use the fans from them? i plan on running three fans two in the rear and a fan from a sony 2 right under the lcd and frens pulling air between them can i run all three fans off one 12v plug and do i have to worrie about the rated milliamps

thanks

Yor 3 fan plan sounds good. You can run all off a single 12V PS as long as thier total doesn't exceeed the cpabaility of the power supply so if you have fans of 180ma, 180ma and 100ma you need at least 460 ma. Anything bigger is fine, if you already have a power supply thats close go ahead but going bigger than needed is always better. So while a 500ma will work just fine a 750ma or 1Amp would be even better.

thanks for the answers
