Okay, now the new server has been ordered, and the full backups have been located. They are somewhat older than what I like, but it is pretty much only blog entries that are missing and I can go without them if it come to that. That said, I get the failed Hard Disk Drive mailed to me so that I can run some recovery on it, if that seem necessary.
The server I ordered is a Dell PowerEdge SC1420. I ordered one with a Intel® Xeon™ prosessor (3.00GHz, 2MB cache, 800MHz FSB) and 1GB DDR2 SDRAM (2x512MB 400MHz DIMMs). It come with a 73GB SCSI Ultra320 (10000rpm) 1'' 68 pin harddisk.
With that, may the old server rest in peace (RIP).
