3-year warranty on system components from original invoice date (system components is defined as all major component inside the case). We will replace or repair any system component for a period of 3 year from the invoice date. If a replacement component is no longer available or is discontinued, we reserves the right to substitute the component for an equivalent part, or offer an upgrade option.
You will receive an official company invoice with a company phone number and warranty information. Should any problem arise, you may contact us by e-mail or by phone. If a return is required, it will be promptly authorized and you may return the system or the affected part for replacement. See store policy for complete details.
