We just sent a new server to our co-lo company (we're in the U.S., co-lo in Canada). We're trying to figure out what to do with the old one. Originally, we had planned to ship it back and maybe put it to use here (although I already have a few extra boxes lying around).
But looking at shipping expenses these days, it just doesn't make any sense to do that. So we're probably just going to let the co-lo company dispose of it after they wipe the drives.
It's certainly not cutting edge- 5-year old Compaq tower, 1.256G RAM, 18G + 27G SCSI hard drives, tape backup & tapes. But it works.
If there is anyone in the Vancouver area that wants to go pick it up, let me know. You can have it for free.
My best friend works at the US DOD Computer Crime Lab. The only way to guarantee data on a drive is inaccessible is to cause physical damage. Take a half inch drill bit and drill through the platters. No recovering from that.
