That mobo isn't recommendable, if you are going into cheapo not interested in OC, go with a520M Aorus Elite, will do the job, after that if you wanna search for a good b450 depends on pricing maybe Steel Legends, or going with b550m Pro4 or b550m Bazooka, those will handle 3700X without any trouble.
Besides that... SSD Less build? Isn't exactly the best option, any decent one will be a experience changer.
And that Case it's just a mess with thermals, maybe phanteks P300A for a better option on the same price bracket.
