Here's my problem with swiftech's design. Granted, it is a MUCH improved version of the Asetek design, with better tubing, pump, radiator, etc., and it CAN be opened / expanded, but how many within the intended AIO market will actually do this "expansion" that Swiftech markets? Within the USA, to avoid a patent litigation, there must be something substantially different that is easily discernible to the average customer, not necessarily "the desired market". Because of this, I must support the legal right Asetek possesses as the patent holder to license (or not license, or make suit) as they wish to protect their intellectual property. One of the parameters in upholding a patent is hostility, which means public use and protection of that patented good.
As such, I support Asetek's right to profit off of their innovation and their right as a business to protect their intellectual property and patents.
