Building a new PC with an ITX form factor we notice that the Gigabyte Aorus x570 itx does not fit with the Thermaltake core v1. The issue been that the metal back plate comes into contact with the standoffs. The standoff design is a ramp on each side and so there is an issue with the fit. The work around for this was to cut off and file down the standoffs on one side. The Motherboard then fits with no issue. Recommend you use electrical tape to cover any bear metal.
