Questions about Thermaltake Core W100

Hello, Does anyone have any idea if you can buy additional disk cages separately together with the hard drive trays or has anyone had any other experience in this regard? Only 3 cages are supplied, each of which accommodates 2 hard disks.

Hello, does the tower come in individual parts or is it permanently assembled? Thank you.

It appears W100/P100/WP100 is no longer available in Europe. That is a sad. Any other big tower case (other than cosmos), that is somehow similar in modularity, and build quality, and air flow abilities? Preferably without side window. CaseLabs is no longer operating either.

Is the height with or without wheels 67.7cm?
