My goal is to build a computer that is aesthetically pleasing, nearly silent in normal use, and has as much overall performance in all tasks as possible. I started with the case, and decided to go with the Little Devil PC-V7 in all white, 420/280 model:
I love the look of this case, reminds me of the old VoodooPC cases. The white looks great in an oak office scheme. I may custom powder coat the case a different color depending on the new desk and chair I go with.
Next step is the radiators. I would like to go with the Hardware Labs Black Ice Nemesis 280 & 420 GTR series. Based on a series of reviews these either the best, or close to, performing radiators at fan speeds of 1800 RPM or above. These will be a tight fit in the fan shrouds of the PC-V7, but I've measured everything out and it should work. In the worst case, I may need to use some spacers or bend metal a bit.
For fans, I'm interested in the Noctua NF-A14 iPPC-2000 PWM and iPPC-3000 PWM. They look and perform the part for this build. Obviously these are not quiet full out but reviews I've read have said the 2000 can PWM down to 800 rpm and the 3000 down to 1100 rpm. I am buying one of each tonight to test them out. I will see if I can tolerate the noise level of the 3000s, if not, I will use the 2000s. Right now, I have no problem with the 1800 rpm fans in my existing build but can notice the 2800 rpm fan on my CPU cooler. The intent on my new build will be to run at low RPMs in normal use or gaming and to only use full speed when stress testing. I will also order the 280 GTR rad tonight to test fitment in the case. If the 280 fits, the 420 should as well.
Undecided on CPU - could go with anything from a Ryzen 5 1500X to a Core i9 7980XE. No needs, just wants.
For GPU, my pick right now is the Gigabyte AORUS 1080 Ti Waterforce WB in SLI. Not really a rainbow RGB kind of person but set to a single color it looks gorgeous:
