Right. I am trying to build my first computer (yay me), and I ran into some problems. So far, all the parts that I have, I have gotten for free, so I wanted to continue that trend for the hard drive. I had an old laptop that I am no longer using, so I decided to try using its hard drive for my new computer. I have an adapter for 2.5-3.5 inch IDE drives, but the power cable that is attached to said adapter has only the red and black wires (2 out of the 4 connectors have wires). are the other ones (yellow) necessary, or can they be skipped? Also, would there be any particular way that I would need to arrange the jumpers on my laptop hard drive, and how would I go about doing so. thanks for your replies in advance Phlip671 New comp specs: -Asus Tusi-M motherboard (given to me by a friend's dad). the mobo already had a celeron processor and heatsink attached.--350-Watt PSU -Being short on cash, I decided that I would use the motherboard's built-in video chipset for the time being (upgrade in future) -512 mb RAM -30GB laptop hard drive -integrated sound card (as a side note, anyone got any suggestions on a cheap graphics card? Not anything top of the line, think 50-60 bucks.
