Can someone recommend a good/better/reliable water pump for the C1??

I keep reading horror stories about those things going all the time, might be a better idea to get a better built pump.

I think I found one on Frozen CPU...

It looks solid and I believe Alphacool is one of the good ones.

You see, I'm good with both computers and cars but cooling systems, I always avoided... gives me headaches.

Would a 600L/h pump work on a system designed for 450L/h?

I like the idea of more flow but don't know if the system itself would take it... again, lack of knowledge on the matter.

Or, even better yet, is there a ready made upgraded cooling kit for the C1?

Lastly, is it possible to use a pair of 650W PSU instead of one big one?

Got lots of smaller 650W PSU's made by Corsair and SeaSonic, a high quality 1000W is a C$200 bill I don't really want right now.
