Customs Official Charged With Stealing Intel Core CPUs for Trade In Credit What Shoppers Should Know

A federal investigation has exposed a troubling incident involving stolen Intel Core processors and other computer components taken from a US government agency. In January, authorities arrested Terry Liu, a 39-year-old supervisor at US Customs and Border Protection, after discovering he had allegedly removed valuable hardware from agency computers and traded it for store credit through an online retailer’s trade-in program.

The Scope of the Theft

The investigation revealed that between late 2025 and early 2026, unauthorized modifications affected 46 desktop computers at the CBP port of entry in Calais, Maine. According to federal documents, 39 of those machines had their processors replaced, six had RAM upgraded, and eight had hard drives swapped out. The modifications were performed without proper authorization from CBP IT management or personnel.

IT staff first noticed the issue in December when they discovered that multiple agency computers had been altered outside of normal maintenance schedules. To identify the person responsible, investigators installed surveillance equipment in a training room at the facility. Within days, footage captured Liu bringing desktop computers into the room and performing component swaps at midnight.

The Target Hardware

The processor replacements proved particularly significant. According to the FBI affidavit, many of the altered machines had their CPUs changed to 12th generation, 13th generation, or Pentium-series processors. Liu’s primary target appears to have been 38 desktop computers containing Intel Core i7-14700 CPUs, which can yield approximately $200 each through retailer trade-in programs.

When IT staff eventually discovered that system performance had degraded significantly, they grew suspicious. The replacement parts Liu installed were older models obtained through consumer electronics retailers, which explained the noticeable decline in computer efficiency. This performance drop ultimately led to the discovery of the scheme.

Financial Impact and Legal Consequences

The actual replacement value of the stolen components totaled approximately $20,460. However, the government’s cost to replace all 46 affected computers entirely would reach $105,800, according to estimates based on current market pricing for comparable systems. This substantial expense highlights the downstream impact of component theft from critical government infrastructure.

Liu admitted to investigators that he had used CBP computer parts in the trade-in program and received store credit for doing so. When first questioned, he claimed he made the changes to improve system efficiency. However, when pressed further, he acknowledged that he knew the modifications would degrade computer performance. Liu later stated he made the changes because he was frustrated with how long it took for CBP IT systems to be repaired.

The charges carry serious penalties. Liu faces counts of theft and destruction of government property, each carrying a maximum sentence of 10 years in prison and fines up to $250,000. He is currently in detention awaiting trial. While Liu holds a US passport and works in a position requiring US citizenship, court records indicate he previously described himself as a native of Guangzhou, China.

What This Means for Consumers

This incident raises important questions about component sourcing and the reliability of trade-in programs. For shoppers considering purchasing refurbished computers or components, this case demonstrates how replacement parts may sometimes come from unexpected or questionable sources. Organizations and individuals buying through trade-in channels should verify the authenticity and origin of components when possible.

For those building systems with Intel Core processors and compatible motherboards, understanding where components originate helps ensure system stability and longevity. The case also serves as a reminder that legitimate computers and parts undergoing refurbishment should come through proper channels with appropriate documentation and quality assurance processes.

Additionally, this situation highlights the importance of system monitoring and IT oversight within organizations of all sizes. The eventual discovery of the scheme occurred only because IT personnel noticed performance degradation and installed surveillance to investigate. For businesses and agencies, regular audits of hardware inventory and performance metrics can help identify unauthorized modifications early.

The incident is unusual in scope and circumstance, but it underscores the value of proper procurement practices and component verification when upgrading or maintaining computer systems.
