My PentiumII sidekick-machine, avatar, was supposed to receive a CPU upgrade today with a Celeron 633 MHz CPU, but alas, PCB revision which supports CPUs faster than 400 MHz must be at least v2.0 and my mobo is only v1.7. Crap.
avatar had a nice uptime of 88 days, but then the HDD failure happened and it's offline since then. 300 MHz have really did a nice job running fluxbox over TightVNC and monitoring the network with Cacti, among other things, including doing the print serving job... I must get a new hard drive for it.
