I understand you are looking for the I/O shield of the Intel® Desktop Board DQ77KB.
My recommendation would be contacting your local Intel service center located in Singapore, there are two part numbers for the I/O Plate:1302-01YL000 (fullheight) 1302-01YM000 (half-height)
http://www.intel.sg/content/www/xa/en/support/contact-support/apac-contact.html Intel contact information for Singapore
You could also check with an http://locate.intel.com/Search.aspx Intel Authorized distributor around your area for more information.
Hope this information is helpful.
The answer I got from Intel Singapore is effectively - motherboard is discontinued, go look up auction sites.
Seriously, I expected a better response than that!
I am sorry to hear that you were not able to get the I/O shield for the Intel product.
At this stage, the best option would be an auction site.
