If you want, that user can move your form by client area, then use WM_NCHITTEST handler to achieve this cool effect:
In the Forms private declarations add this
procedure WMNCHitTest(var Msg: TWMNCHitTest);
message WM_NCHITTEST;
Create handler for this message with this code:
procedure TForm1.WMNCHitTest(var Msg: TWMNCHitTest);
begin
DefaultHandler(Msg);
if Msg.Result=HTCLIENT then
Msg.Result:=HTCAPTION;
end;
