Hard disks upgraded multiple times, though mostly to avail of increased speed and capacity. Same with DVD-Writer module.
Front memory slot failed, a common problem with old T30s, but fixed by putting a 1GB module into the rear slot.
Fan failed recently. Bought a replacement on eBay and replaced it myself.
OK, so there have been a few problems, but nothing so fundamental I couldn't fix it myself - thanks in part to this forum. The keyboard is still absolutely fine, as is the chassis, hinges - unlike so many non-IBM laptops, screen - still bright enough - and of course the motherboard. So kudos to IBM/Lenovo, they seem to know what they're doing alright
