If you’re asking about the TEC from the previous thread that’s the FS12-45 Tablet cooler and is ~$29
The QUICARD I’m replacing the TARGUS with is $69.99
The Acrylic Stand and TEC is $39.99
The actual “rack” idea with proper fans and TECs was over $4K and was not worth the build for minimal impact given how insulated the Sparks are.
