I'd pick asrock b450m Pro4. It's around 25k HUF, which is roughly 77€. Will support 8 rams, and the wraith stealth cooler of the ryzen2200.
Another option could be b450 DS3H, being slightly cheaper, around 75€.
But if your budget is 100€ you can even opt for b450 aorus m, or b450 mortar / bazooka.
These are from 90 to 100€ in price. All three of them ( aorus, mortar, bazooka) worth the price.
Do You have preferred ideas for memory?
