Motherboard is of true N900 (with possibility of being after-repair one), other parts are chinese replacement (including LCD?).

All N900's (except early dev devices) were made in Korea. "Made in finland" is mistake found on replacement bodies, both high and low quality ones. "Dexigned" is funny mistake (of screen's backplate) and indicate chinese replacement part for sure, but nothing worrying.

What I would be concerned of, is fact that LCD/digitizer may be of lower quality than original one (MyPaint is good program to check digitizer's response).

Never had problems with N900s from China. If they can run Maemo 5, they are good to go and work as well as the one I bought in USA made in korea. The ones I bought from China look like new. Love them and keyboard is the same as KOrean ones. So whatever they did to retrofit, they did a great job.

i have 3 n900
two were made in korea
and one made in finland

the finland one can overclock to 1150 but the korean ones only to 950\
what do you think ?

I think that it's complete absurd - you can overclock every device to max, given enough high voltage is specified in config file. not to mention, that decoration, written in replacement part of body, doesn't seems to affect overclocking much

Still, over-clocking to anything above 900 mhz is stupid thing to do, as it doesn't give any real benefit* (pure numerology), and stress device a *much*. Also, freemangordon's SmartReflex works reliably for up to 900 mhz (kernel-power only), which means battery savings.

*MyPaint may be exception here - famous N900 painter, CreativeTone, claims that MyPaint draw line is responding faster on 1150 mhz. Honestly, on my device it acts exactly as quickly (real time) on 900 mhz... so, it may depends on other things, like settings related to swap, thumb2 + updated compiler, etc.
