A friend gave me a dimension 8400 desktop that he said was broken. i know some about computers and tried to see what the problem was. everytime i turn the computer on, the cpu cooling fan goes crazy...

Thanks for the information, pretty detailed, I recommend you get all the specs of the Dell dimension 8400 motherboard and buy a compatible one, of course check the CPU first at a friend's home and if the CPU is fine, go ahead and buy and install a new one.

One of my disc drives on my Dell Dimension 8400 is stuck open. i have a Lite on Model LTN-486S that i took out of a Dell Dimension 4800 that was broken. is it compatible with mine?

Should work fine. Only issue you may run into is getting the cable settings (master / slave) set up so everything shows up. Most likely if you're replacing an existing one you can get away with just setting the new drive to cable select or what the previous drive was set to though.

Please leave feedback if this was helpful.

Unable to remove cover from dell dimension 8400 desktop pc

This Dell Support, and the Service Manual for the Dimension 8400,

In the Service Manual main menu, left-click on - Opening the Computer Cover

1) Computer off, and unplugged from power. (Always unplug the power cable from the surge protector. Then if the power cable needs to be removed from the computer, do so)

2) Remove all cables to the computer

3) Lay the computer on it's Right side.
(As you face the computer, your right side is the computers Right)

4) There is a Release button on the Top of the computer case, and a Release Button on the Bottom of the computer case.
These are located at the Rear of the computer.

The preferred method of opening the computer case, is to press one release button in at a time, and slightly lift up on the side of the computer case, where that release button is located near.

Then go to the other side of the computer case, press this release button in, and lift up on the computer case.

The computer case opens like a clamshell. The computer case is hinged at the front.

Computer laying on it's right side. Press the Top release button in, and lift up on the computer cover located near the Top.

Now press the release button on the Bottom. Lift the computer case up.

The computer case opens from the back, towards the front, like opening a car hood.
