For small computers, e.g. with CPU TDP up to 30 W, being fanless is a great advantage.
(The case should better be completely closed, otherwise dust accumulation can reduce quickly the efficiency of a passive cooling solution.)
Small fans are always very noisy and, with few exceptions, in such small computers the fans are the first component that becomes defective, after a few years. Moreover, for small fans it is frequently difficult to find an appropriate replacement fan.
None of these problems exist for larger computers, i.e. for Mini-ITX and larger cases.
In such large computers you can use large low-noise fans, which cannot be heard if the case has good enough acoustic insulation.
Moreover, good-quality large fans can have a very good reliability, i.e. a lifetime of at least 10 years is easily achievable and they are easy to replace anyway.
In conclusion, while for small computers I also always attempt to use only fanless computers, for large computers I do not believe that it is worthwhile to accept the much larger size & weight that is required for a fanless computer at any given TDP.
