I'd expect your T400 is similar to my E6510 in terms of construction since they're both business machines from the same era. The E6510 is a tank. The hinges are still solid and there's no wear on the keyboard. There's a single panel, held on by just a single screw, that pops off on the bottom to expose the majority of user-replaceable parts.

It'd be useless with Windows, but works great with Linux. The only issue I have is severe lag on google maps.
