Recently built my first PC, parts listed below. Didn't have a wi-fi adapter at first, but after issues with my university's internet I've bought one.
This comes to the graphics card question, I'm unsure whether to mount the cards as shown, with the graphics card in slot 1, the preferred slot, but essentially block off half of one of the fans, or move it to slot 2 and move the wi-fi card to the first PCI-E slot. Any suggestions? Can attach more images or information if needed. Haven't done temperature tests but let me know if you recommend testing anything or if there's a flat out best configuration for this.
