I bought this Dell GX280 to upgrade my cousin's existing Dell. Not only did it work as advertised but I was able to swap hard drive, ram and graphic cards from the existing Dell to the one purchased; saved me hours of work. This wasn't the cheapest one...

I ate the loss and trashed the thing. Research the Optiplex before you buy. My big mistake!
