Ask HN: Please recommend the best pre-built itx or laptop (details inside)

please recommend the best detailed analysis/review of the best pre-built itx computer with at least 16g ram, 25-50+ ssd, no other key requirements, in 2017 a comparative review comparing to other best itx computer options would be best -- or a detailed analysis/review of a laptop that has very very low heat, the analysis/review should say what temp the laptop is at regularly (heat negatively affects performance it seems)
