Assembly Proxy Service with Half-Price Coupon

Recognizing that PC assembly can be daunting for some, PC Kobo offers an assembly proxy service. This service allows customers to have their PC professionally assembled by expert staff. Orders for an assembly kit and the assembly proxy service are scheduled for shipment 5 to 7 days after the order date.

Assembly Service Half-Price Coupon

Customers purchasing the aforementioned assembly kits are eligible for a half-price coupon that can be used at PC Kobo stores for assembly services. When requesting the service, customers need to present both the purchased product and the coupon.

Available services and pricing with the coupon include:

“Assembly + OS Installation + Driver Installation”: Normal price 20,000 yen, coupon price 10,000 yen. PCs assembled with this service come with a 1-year warranty.
“Assembly Only”: Normal price 10,000 yen, coupon price 5,000 yen (available at stores only). PCs assembled with this service come with a 30-day repair warranty.

Furthermore, if a customer attempts to assemble the PC themselves and encounters difficulties, the same coupon can be used at stores for an assembly failure proxy service, priced at 12,000 yen (normally 22,000 yen). This service covers assembly only and does not include OS or driver installation.
