Building a pc for the first time, just a few questions ...

First of, how are my specs :

Desktop = Dell Inspiron 5100

Video Card = nVidia Geforce 9800 GT 512mb

Prosessor = Intel Core 2 duo

Also, do desktops have a built in wireless.

Not many specs listed, but the video card is ok for moderate gaming depending on your display's resolution. Don't expect to have everything cranked up high for the latest games though. If you're planning on gaming on anything above 1680x1050, would be a good idea to get a more powerful card.
