I have never tried to build anything small so don't know where to get cheap parts or what to get. Here is what I want to do: build a resonalbly 1.4 gig proc, fast embedded video for kids games (no major 3d), in a case no more than 12 inches deep, 14 inches wide and 4 inches deep. Also need a cd drive and Nic. I want to mount it under the cabinets like a can opener. Have lcd already and making custum keyboard/mouse drawer. Any advice on what components and where to get cheap would be great, want to go as cheap as I can. Thanks.
