You can buy a voltage transformer that steps you up from 110v 60Hz to 230v 50Hz. When you plug in 110v I don't think anything'll happen or go phut - but that's a reasonable guess. You could simply replace the PSU with the same output wattage and form factoe local brand. Perhaps 30 minutes work but with care.

On Windows install, just buy a US/Canada keyboard and set your region and language settings in the currently installed Windows.

The two LCD screens I have use a DC transformer which has a 100-v-240v/50-60Hz range. If that's the same with yours, just stick a Canadian plug on the end and cut off the European end; or plug a mains adapter into your plug and pplug the screen in directly. Do check that you have this transformer as part of the mains chain or else it'll go flash.

None of this is a big deal and you're nearly ready to go once you've dealt with the computer's PSU.
