At the moment nowhere, I've contacted Gigabyte who were beyond useless, then I contacted every site I could find which listed either the manufacturer part number, UPC code or product code, with places having it listed but none actually having stock or able to give an ETA of the re-up. Very annoying Gigabyte conversation went along the lines of:
Me: I'd like to buy this part
GB: Please see our sellers list
Me: Local Distribution didn't get stock
GB: Not all regions received stock
Me: Can you tell me which regions received stock?
GB: See our sellers list
Me: Can you narrow it down slightly?
GB: *crickets
