Re: Legality of third party fans
This rule bothers me. DC powered "computer" fans are pretty ubiquitous, using a different brand/model isn't going to give you a competitive advantage. On top of that, it's borderline unenforceable....

Re: Longer Talon SRX Data Cables

Re: Question about Anderson PowerPoles
Could you post a link to which particular powerpoles you purchased? There are a couple of different product lines with the powerpole name, and it would help to know exactly what we are looking at.
