What's The best budget Tempered Glass case?

Solution
While maintaining good build quality and having meshed front panel (for good airflow), i'd say best budget case would be Thermaltake Core G21 Tempered Glass Edition,
specs: http://www.thermaltake.com/products-model.aspx?id=C_00003106
pcpp: https://pcpartpicker.com/product/Q6YWGX/thermaltake-core-g21-tempered-glass-edition-atx-mid-tower-case-ca-1i4-00m1wn-00

But the best looking case with TG side panel and good airflow, while being affordable, in my opinion, would be Sharkoon DG7000-G series.
Note: it's only available in Europe and not in USA,
specs: https://www.sharkoon.com/product/1678/DG7000-G
pcpp: https://de.pcpartpicker.com/products/compare/Yrbkcf,4CRFf7,f8tWGX/

My AMD build sits in the Sharkoon case, full specs with pics in my sig.
