Shopping 3 + attempt to build

Yesterday I ordered the memory (1024MB DDR RAM 400), but there was some delay in the e-mail with the payment and only this morning I could see it and respond, so only tomorrow ( if the speed on delivering is still the same) I should receive the material, so during the weekend I can try to mount what I have. Yesterday I already tested it by placing the material in a box of one old satellite receiver Echostar 8200S, I've removed the interior parts and tried to see how could I distribute the material, the DVD ROM drive will not be placed in this box, but in the compartment that my car, top center console, as in England this friend Paul (cambo) did http://www.cambouk.com/carpc, with a car equal to mine.
