I have an old UltraEnterprise Sparc 2 Server that I am not using anymore.

In it's day they were great boxes :)

I have the following in it:

2x18GB 80 Pin disks SCSI disk in the box
2xExtra sun SCSI disk holders to allow you swap the two disk in the server for another two disk if you want
1xYamaha SCSI CD Writer inplace of the regular Sun CD Drive. It happily boots Sun bootable CD's plus it can write CD's as well

Update: Here is the boot splash via serial console:

Sun Ultra 2 UPA/SBus (2 X UltraSPARC-II 296MHz), No Keyboard
OpenBoot 3.25, 1024 MB memory installed, Serial #8537212.
Ethernet address 8:0:20:82:44:7c, Host ID: 8082447c.

I think there is 1GB of ram in the box, and I think there is 2x300Mhz/350Mhz CPU's (I know it's a dual proc, just not sure of the speed), will power it on this evening and see how much is in there
Plus I have a Sun Keyboard & Mouse so you don't need to have a serial connection always there.
I used to have a 26" Sun monitor to go with it, but a colleague blew it up by plugging it into his laptop (idiot!)... So you can get a Sun Video connector to VGA connection off Trademe + other places if you want to connect a regular monitor to the box.

PM me with an offer for pickup in Wellington
