Need a good PC case that doesn't break the bank

[senpaikiller9]

Finished picking my PC parts

CPU: Ryzen 1600
RAM: Ballistix sport LT,grey 16GB
Motherboard: MSI B350 Gaming Plus
HDD: WD Caviar Blue 1TB
SSD: Samsung 850 Evo 250GB
Graphics card: Sapphire Rx 580 8gb Nitro+
PSU:
Corsair – 9020133 EU TX M Series Part Modular 80+ Gold

But I need a case
I wanted the NZXT S340 but it's out of stock 🙁
Really need a nice case with a good airflow ( I don't really like the "gaming" look tho )
I'd like something similar to an S340 if possible.
Thank you for your responses!
