For sale is a used Intel X550-T2 Full Height network card. PCI-E 4x. It features 2x 10GbE RJ-45 ports. Purchased from a local office who were selling off old hardware. PCB has a slight distortion to it, was like that when I got it. Hasn't affected functionality. These run quite hot so I would recommend you strap/point a small fan to it if using it in a regular desktop computer. Has been rock solid in the past year of use. Only selling due to upgrading my home network to full fibre. No original box or accessories. Just the card.
