Hey guys, just a quick update and solution for the backplate issue on the Tuniq tower 120 on mobo's. the solution I found was buying some "Kavan clips" . these can be purchased at any hobby store that sells radio controlled models. The cost is $2.00 USD for 6 kavan clips{you only need four]. These are heat resistant plactic linkages use on R/C model Aircraft , and Cars with gas engines. when you get them home, cut the heads off using a dremel tool, and use it as a spacer between the mobo, and the metal backplate. the o/d is perfect for the screws, and the thickness makes it impossible for the backplate to contact the back of the motherboard, or crush component. It works perfectly with the mobo mounting bolts to the case with clearance.
have fun , and enjoy!
