This is one of the now infamous models that had Bad Capacitors.
Dell Optiplex GX280 Capacitor Kit
Photos showing Dell's Optiplex GX270 and Optiplex GX280 with defective capacitors have been widely reported on Web sites such as Badcaps.net, PowerEdgeForums.com. Pictures of other faulty capacitors have been spotted on Apple's own discussion boards, MacOSG.com, and G5Support.com.
You can inspect a cap to determine if it is bad visually and otherwise. If it has the indications of swelling, brown ooze, domed top, brown ooze at the bottom, it gets VERY HOT to the touch. You may also hear of Capacitors described by the cuts on the top aka X or T or K or Y.
