Dell Inspiron 3650 Intel i5 MT Desktop

I have an older version of this PC. This is a nice deal for someone who wants a desktop instead of a laptop. The specs are good and it should be fine for a solo or small firm professional or a small business.

Mine has been rock solid reliable and runs very quiet. No perceptible fan noise, which is nice for an office environment. Mine lacks the dedicated graphics card this one has. This one would be ideal for running two monitors.

Any idea if this pc is downgradeable to Windows 7?
