Semi-OT question.

My old, recently replaced, laptop is suffering from nothing worse than a completely shot LCD panel. I'm considering replacing the dusty old HP Pavilion I use as an all-purpose server with the laptop.. any thoughts on this plan? Would it be a bad idea to leave a laptop running 24-7? I'm running the ever-unpopular (at least on this forum) SuSE Pro 9.1 on it right now, so adapting it to a server box would be no big problem.
