> DVD-R (gold metal layer) 50 to 100 years

These are the only DVDs listed with such a long life. I don't care about RW. Anyone know a brand/model of such DVDs I can still buy today?

I really dig my "Be Quiet!" tower (Pure Base 500 / military/beige color) but there's no 5"1/4 slot to put a DVD reader in there. It pisses me off so much I may re-assemble my modern PC in an old case : (
