Installing The CD-ROM Drive

Building Your Own PC, Part 2: Assembly Step by Step
By

Installing a CD-ROM drive is similar to installing a hard disk. First, check that the jumper configuration is correct.

You only get to see the metal below the decorative plastic front panel when installing your system; the case metal is actually hidden by plastic panels. The entire front section, or at least the part where the drives will be installed, is manufactured from a single, large piece of metal, in which the drive holes are then punched. For some years now, the CE norm for cases has specified this kind of metal panel, as only metal can reduce electromagnetic emissions - the processor usually being the worst offender in this area.

In practice, there are two options. If the metal knockouts are pre-stamped, you have to either take them out using metal cutters, or knock them out using force. If you have a high quality computer case, you can remove and replace these metal panels whenever you like. Check carefully to see if there is an easy way to remove these panels that will reduce the chances of your accidentally damaging one or more of them.

When we have opened up the hole, we can feed the CD-ROM drive in and screw it into place. You will need the fine-threaded type screws. Always use four screws. Be careful not to over-tighten the screws, as excess pressure can put a strain on the case that could lead to twisting. The faster a drive's rotational speed, the more serious the effect. Tighten the screws only enough to ensure that the drive is secure. Heat is a consideration with CD-ROM drives, as it is with disk drives.
