Just wanted to leave this for people searching if it is possible to put more 3.5" hdds into Torrent Compact case.
With some creativity I was able to add fractal design cage for 2x 3.5" hdd at the bottom. But I am not using the bottom intake fans. I only use the front case fans.
The hdd cage It is from my older Fractal Design Define case accessories.
I repurposed the “GPU support bracket” that is provided with Torrent case to hold the hdd cage in place so it doesn’t travel. I screwed it to the hdd cage and to the bottom of the case. It wasn’t exactly easy, the manipulation space is tiny, I helped myself with temporary tape to keep things in place until I was able to screw it in. Also note that this is not possible without magnetic screwdriver.
Cables for additional hard-drives go through the hole in the bottom corner, 2 sata and power cables, they pass just barely, but they do.
So this gives me total of 3x 3.5" hdds in this beautiful case with those gorgeous 180 mm fans in front.
Also I changed the passive cooler for the chipset (x570) for Primecooler PC-NBHP1 because it was the hottest part of the system after few days of test run.
