@All - thank you, I'm pleased.
@rontant - Obviously it's not just any fridge put in any cabinet. Both the fridge and the cabinet are sold as one specially designed system. The fridge's door is attached to cabinet's door so they open as one piece. And the cabinet itself is designed to dissipate heat. If you take closer look - there is a vent grill at the bottom of the cabinet. It sucks in the air, the cabinet has no back side and all the shelves have cutouts to enable gravitational airflow. The top of the cabinet doesn't reach to the very ceiling, there is a gap for a reason - there's the way for heated air to come out from the system. Maybe the energy consuption would be a bit higher but this system should work even at 30C.
I never said that it takes a week to render one picture, on my usual settings it takes 45-50 minutes.
In the following case I wanted to recreate the photo I posted above, so i used GI:Path with just 1 bounce. It took 9 hours and 30 minutes to render - that's what I ment by saying "a week or so".
My computer specs? - Don't even ask :) For the last 8 years I've felt like it never gets old, it was good enough to browse Internet and play tanks, but since I've started rendering pictures I realized it really needs an upgrade, maybe for something like UbuntuBirdy announces :) Definitely Ryzen and insane amount of RAM... Display card doesn't matter here - it's a pity as mine is quite powerful even as for todays's standards
@EnkoNyito - thank you, I believe it's your light sources that made it possible, the're really game changer
And finally a picture - it looks that using GI:Path changes a bit the colour of the kitchen cabinets fronts to darker. Probably because they consist of two layers of material - external gloss coat made of "glass" and internal being an actual color. I made them in Blender this way to get rid of that horrible glittering reflections caused by silk shininess shader. And yes - I tweaked badly the brightness and light temperature :/
