Re: So...a whole new computer?
oldest a pair of CRTs from 2004
Can't remember what age the CRT attached to my monitor is (it's a 21" Sun-branded monitor and I left the job where I obtained it in 2002..). Admittedly, the only time I turn it on is when I'm rebooting the server - which is about twice a year when a kernel upgrade requires it.
The server it's attached to is a Supermicro quad-xeon that I got about 3 years ago. All SSD drives :-) A lot more queit (and generates a lot less heat) than the Dell 2950 server that I used to use[1]- that one had 6 15K RPM SAS drives.
[1] Still in the acoustic rack, underneath the new server. In a pinch it could run the important subset of VMs that the new server currently hosts.
