Getting Snow Leopard on my ancient Mac Mini

[Spinball]

Hello,
I'm posting this from my Mac Mini which I bought in 2006:

Machine Model: PowerMac10,2
CPU Type: PowerPC G4 (1.5)
Number Of CPUs: 1
CPU Speed: 1.33 GHz
L2 Cache (per CPU): 512 KB
Memory: 512 MB
Bus Speed: 167 MHz
Boot ROM Version: 4.9.4f1

MAT****ACD-RW CW-8124

I need to get Snow Leopard on it so I can get a digital certificate to publish an iOS app.
It doesn't matter if the machine is dog slow after it's installed so long as I can get the certificate.
But it might be nice if he machine is usable. Is it a case of getting my local Apple store to upgrade the memory?
Thanks

The maximum OS for that PowerPC is Mac OS X 10.5.8, Mac OS X 10.6 Snow Leopard requires an x86 (Intel) CPU.
