Great price and product. There is only an ethernet connection which is ok for me. But a WIFI interface would be nice as well for some of the design work I am doing. But this is not a real problem and had nothing to do with my choice in buying this product. I have plenty of ways around the WIFI concern. You get a lot of bang for the buck, there are even two RS232 ports in addition to over six USB ports.*******************************************************Whoops! It does contain WIFI - in the form of a USB plugin adapter. Wow! This is without a doubt the best computer purchase I have ever made, and it's a rebuild.
