The most important part of this mod is the fans the best price for them is on Amazon.

Noctua NF-A4x20 FLX - amzn.to/2Mb5aH4

Same fans/mod for S2500-48P S2500-48T S2500-24P S2500-24T

The other tools I used that can be substituted for what you have on hand.

• #1 Philips Screwdriver (precision works best)
o amzn.to/2SXx0cv

• A Drill with a 3/16” Bit (widen fan screw holes)
o amzn.to/2VSYIsO

• Wire Cutters or Scissors (cut wire management ties)
o amzn.to/2VSYIsO

• A Dremel with a Sanding Bit (to file away the fan connector to fit)
o amzn.to/2suGLDj
• Vice Grips (to Hold Fan Connectors)
o amzn.to/2stg1TF

• Cisco 3850 Brackets and Power Cable
o amzn.to/2SSLieh

• M4 8mm Screws (For Brackets)
o amzn.to/2suJ0GJ

Since the switch was so cheap I did not mind investing into it a bit to make it even better, and now I have a one of a kind S2500 and got to enjoy a fun DIY project.
