We decided to buy these cases because of a good price and to save time on manufacturing, however in the end, custom made ones would probably be better...
1. there is only one handle on the front cover (obvious from the pictures) which is very impractical, so we bought and mounted two additional AH 3412 handles per box and mounted them on the two sides where latches are
2. the latches bend very easily so we will see how long will they hold up
3. sliding rack strips are only on one side (again obvious from the pictures), however the used profile is around 20mm wide so our attempt to add AH 6162 rack strips in the back failed because it is too wide, maybe AH 6161 could work, but we used 3D printed holders to mount PDUs
4. the logo placement on the top side interferes with the foot of another rack stacked on top therefore the upper cases are rocking, so we removed the logos completely
