Get yourself a KenWood True 72X on SCSI Ha ha! Just kidding. You can find yourself a new CD-ROM for about $20 (if you do a little looking, otherwise it might cost you $50).
As the guy above mentioned, buying OEM helps (bare bones, no fancy retail box with instruction manual, etc....)
If you really want to consider quality (in which case you will be paying $50 instead of $20), PlexWriter is famous for making the best CD based products (though they mostly do burners, they have CD-ROMs as well).
Most drives are 52x Max (some are 48x, like Mitsumi; some are 56x, like Acer - but most are 52x).
If you don't have one right now, it might help calm you down to get a shielded UDMA 66 IDE cable. UDMA 66 cables are 40 pin, but have 80 wires running from them (regular cables only have 40 wires and will only run at ATA 33 - 66 cables will let you go as high as 133 - though currently the only drives running on that ATAPI interface are harddrives made by Maxtor, no CD-ROMs - most other harddrives are ATA 100 - and most motherboards supporting 133 have it on a RAID interface - am I confusing you yet?

). You can tell because there's obviously twice as many wires, and they are much thinner (they are finer, and feel smoother).
Shielded cables have extra protection on them. Helps ensure that the signal is not interrupted by static and loud noises (if you happen to keep your PC inside of a nuclear power plant

) They sometimes have extra rubber wrapped around them, and are blue in color (as opposed to most IDE cables which are white/gray)
They cost $20-30, but are not necessary (it just might help your sanity a bit)
Just attach it to your secondary IDE channel and your drive. And as that guy mentioned above, you'll also need your power supply, and your CD-audio cable (if you want to listen to CD music).
Oh, and don't forget, while it will likely be done for you, make sure your jumper switch is set to master for the drive (instead of slave).
There, is that a thorough enough response?
