It doesn't have to be made in USA to be good, in fact, it can be just as crap as the crappies one you find made elsewhere... Mine is Made in China but what makes it good is the quality control. Bosch does not give out his name just to get it dirtied by crappy quality, it is made in China by Bosch in their own factory and under their own quality control. Basically everything is made in China, which does not automatically mean crappy quality.
I don't know the Nowforever "brand". I helped out once a Swedish forum member with his Nowforever VFD but that was regarding the use of Modbus to control the the VFD. The manual was good enough to make it running and as far as I know, he is (or was after that) happy with it. I think it is wrong to buy everything in a kit believing you can get excellent parts for nothing. I think buying parts separately gives the best results with the most optimal quality. If I'd buy a water cooled I'd look at the quality of the pump as well and would not buy a simple and cheap fish tank pump which may fail a few days after you start using it, or would be annoyingly noisy or pump with rigid jerks or some other things which may go wrong with those. But again, that's just me.
