ATX vs mATX vs ITX - What's the pros & cons of different motherboard sizes!

I built am ATX and the next one im building will be an ITX

Thank you there is so little info on DTX or ATX!
Do you know if are there any DTX or ATX boards suitable for the AMD 7000 series? (AM5, PCIe 5.0, M.2, DDR5)
I can find 5x Mini ITX; ASUS ROG Strix X670E-ITX, ASUS ROG Strix B650E ITX, Gigabyte B650 ITX Aorus Ultra, MSI B650 ITX & ASROCK B650E PG-ITX
But I can't find any DTX or ATX?

Thanks

Hi,

I am looking to buy/build a PC

My current budget is 900-1000$ don't want RGB. I am also looking for a good motherboard which would support future upgrades for RAM etc... And also if I can install a good GPU in this same budget. for 1080p or 1440p resolution whichever works with the budget.
Can you kindly suggest configurations

Thank you! Great video. :)
