Yes, high quality movies, lots of tabs (browsing), may be Photoshop too.
Quiet
, stylish, compact box (with less ventilation holes (surfaces) = dust). Not too expensive.
With it, the main difficulties are the power supply and video card. But with Ryzen 5 5600G (I don't think I will need a GPU, in near future.)
Cooling: ID Cooling IS-55 (31.2 dBA?), [Thermalright AXP90-X53] (( DEEPCOOL AN600 R-AN600-BKNNMN-G))
RAM: 2x16GB
memory: I think only SSD (1TB)
ITX MB with two video ports.
Exam:
ASROCK B550M-ITX/AC 90-MXBDH0-A0UAYZ
ASRock A520M-ITX/ac
so... better options under $150-180 ?
/different from Asrock?/
Power Supply: I think 450W is enough.
SilverStone SST-ST45SF v 3.0 - SFX Serie, 450W 80 Plus Bronze = 87E
be quiet! SFX Power 3 450 W, 80 Plus Bronze, 68E
Seasonic Power Supply 650W Focus-SPX-650 Modular 158E
What about : Fractal Design Node 202 + Anode SFX Bronze 450W (fabric) = 175E
During that time I was looking for other cases (11-15l), but I liked only these:
LIAN LI Q58 https://lian-li.com/product/q58/
(D) 342mm x (W) 170mm x (H) 250mm 14L - but no more black (only white)
Lian Li A4-H2O = DAN Cases A4-H2O, (H) 244mm,11L - it has many holes... but 159.90€
