I hooked up the new heater core and everything, and started bleeding the system. It seemed to have a lot of air bubbles lately, but I just ignored it until tonight...
I start wondering why after like half an hour there are still plenty of air bubbles, so I go and lift up the pump off the bottom of the case, and it's covered in water

Stupid freaking Swiftech MCP300... Add me to the list of people who have had the pump crack and leak on them :\ I dont know how Swiftech can conscienciously continue including this POS pump with their watercooling kits.
It's a good thing I didn't leave it in the stock fill & bleed drive bay thing ncluded with the kit, or else my entire system would be covered in water.
I'm going to email Swiftech, and make them send me a refund, with which I will purchase a good pump.
Any suggestions on something that I can get for cheap, but won't crack/leak on me?
