plug in card reader for old Dell 4500c

I am rebuilding an old 2002 Dell Dimension with a card reader socket. Can anyone tell me where to find this part. The tower is the clamshell design that opens by pressing two button on top and bottom.

 

Greetings, dreed101.

Need to know what operating system you're going to run, as well as the motherboard specs.

 

Machine is Pentium 4 with XP operating.

 

Look on the case for any labels that will show the Dell Service Tag #.

If the machine is running, then please download and install Everest, a free system information tool.

Run Everest and click Report (top menu) > Report Wizard > Next - Choose System Summary Only > Next - Choose Plain Text > Finish and wait for report to generate.
Click Save to File and leave the File Name as Report, then click the Save as Type dropdown and choose Report files (*txt) - click Save (n.b. Save to desktop, use Browse to locate desktop).

Then attach your log to your next post per these instructions: HOW TO: Attach Items To Your Post.
