This machine is a tank of a server! It booted just fine after 15 years in storage, no issues at all!
But it takes its time doing a lot of internal checks after powering on, the boot time is about 3min. And it makes a lot of noise. The fans are starting already when plugged in, even before pressing the power button!
Its modular design makes it very easy to change and replace parts, no screwdriver or other tools are needed. Almost everything is hot pluggable: PSUs, fans, disks, PCI.
It’s default configuration is as tower model. But when removing its feet, it’s exactly 19″ high to fit in a rack. IBM even sold rack mount kits to convert the case and add rails.
I mainly used it as an VMware ESXi host. But replaced it later with less power hungry servers.
