3060 ti mining rig questions

Hello,i am buying 3060 tis soon and want to know what mobo should i use? For now i will get 6 gpus but want to expand in near future.So the question is what mobo should i use?What PSU will suit?I dont know if i should try to build one 10 gpu rig or should i build two 5 gpu rigs.Or maybe two 6 gpu rigs.I think two mobos with 6-7 PCI-e links will be fine or should i choose to buy Asrock h110 pro or biostar btc pro?Anyone went through all of this to share experience?
