We've seen impressive 3XS hardware from Scan in the past and their Cobra SLI systems don't buck that trend. Incredibly well built, paint jobs to put others to shame and potentially umatched performance round off maybe the most impressive systems I've had the pleasure of working with to date. If you're looking for high-end SLI right now, I can recommend you put an enquiry or two their way, for the configuration you're looking for.
