I'm just finishing a client build in the RV02 and its a joy to work with. Only problem is that there might be an issuing mounting any cards bigger than the 5850 (Toxic) I put it. I think some people have put in 5870(s), but this 5850 particularly has the two 6pin at the end - I almost couldn't get the cables to fit in with it (you can see this in the build log I put up). Luckily, they did get in no problem
The stock 180mm fans also run pretty quiet when at the "
low" setting.
I can't speak for the RVo1, as I have never used one before.
