Hello dear Sun power users

I'm andy,from Italy. I would like to make some
experience with the Ultra Sparc "world" but I don't have a lot of money. I
see that there a lot of cheap Sun ultra 5 systems with generally 360mhz 256k
cpu's and 128mb of ram. I would like to buy one ultra 5 and install some
solaris/linux/freebsd and in general *nix system but I don't know if this
configuration (360mhz -256k,128mb,8gb,ati rage 4mb) is enough for making
this...of course I don't need to keep multi-boot so I would install just one
O.S. each time. Could you help me?It's time to change this freak x86 pc

bye bye and thank you!
Andrea
