I've been offered a Sparc 5 for a good price, I've also found a place knocking out Sparc 20's as well. My two questions are:

Question 1: How do they compare? The 5 has a 70Mhz processor, not sure about the 20, but they both have 64MB and decent sized HD's.

Question 2: Should I stick with Solaris or put Linux on it?

The machine will be used for routing, NAT and firewalling. I may very well get both, but I just thought I'd ask. My experience outside the wintel arena has simply been linux on x86 so I'm not that familiar with the Sun gear.

They do look damn cool though!
