Register your components and shipment details, upload an invoice or proof of purchase. (Note: Claiming these PCs requires the 'Serial Number' and 'CHK' number of each component. If you didn't receive an invoice with your product serial numbers, you can email us to request one. When entering your product serial numbers, you will also be required to enter each product CHK numbers. When logged into your MSI Profile, you can 'Submit a ticket' under the support section of your profile. Submit a ticket asking for the CHK number for each of the products on your invoice. You will need to product your invoice with the serial numbers on it for MSI to get back to you with the CHK numbers for your components.)
