I used a cat6a shielded wire from Monoprice. A header like these to avoid soldering on the F-1 (the f-1 comes with a male header, I soldered it on however). https://www.ebay.ca/itm/20PCS-2X10-...ield-/351494232951?hash=item51d6b05b77&_uhb=1[ And a cord grip like these: https://www.ebay.ca/itm/2pcs-M8-Wat...-5-7mm-Wire-/321715241257?hash=item4ae7b90129 I soldered the rj45 to the male part of the header, a the bottom, then trimmed the pins so that all fit in my case. I suppose there is enough room in the case that now is available from singxer. I had to remove the jacket and shielding for the wire for it to pass through the grip's hole. The grip being metallic, no shielding issue there, assuming it matters in the first place.
