Its their money, if they want to waste it, who are we to stop them?
Cooler - Deepcool AK400, unless going other way for aesthetics. Remember that i5 13500 can draw 150W on full load, so needs a good single tower cooler or dual tower dual fan one like AK620 as India has high ambient temps.
Mobo - Get MSI B760M A Pro WiFi
Cabinet - Deepcool Matrexx 40 3FS looks good & is compact as it is a mATX case, so no ATX mobo support
