The SG10 Copper Edition is a limited production run of the SG10 that features a fully copper condenser. This special version of the SG10 is dedicated to the Kickstarter Community as a token of appreciation for their project support. All 500 units have been allocated to them, but not all backers still want the product, so those unwanted units will be made available to the general public. To purchase one, you must first buy a pledge voucher from Calyos so that they can refund the backer and make that unit available to you for purchase. The voucher can be purchased from sg10.calyos-tm.com, and once you have this voucher, you can use it on the Streacom shop to enable the purchase process at shop.streacom.com/products/sg10-copper-edition-fanless-gaming-case
The total voucher value is discounted from the retail price at checkout.
