Reference material for mining and rigbuilding

My gpus are starting to come in the mail and I have more stuff coming but I’d like to find a magazine, website, or crypto mining resource other than youtube in general… id just like a deeper understanding before I fry some of these or break stuff assembling and subsequently connecting to an ideal pool etc… I have some rtx cards and some amd 6600xts to start and ideally will get decent cards as I’m able in stock locally vs resellers… any dos or don’t when mixing brand cards etc? If you learned a lot from a soucenplease reply it here and appreciate that in advance!
