120V pump to on/off switch

[elninio]

I have a via aqua 120V pump, I want to connect it to the computer such that when the computer turns on, the pump will also be turned on. When off, so will the pump be off. I have seen someone do something similar to this, I think it was with a pump and a temp probe, does anyone recall the link? The trick here is that the pump is 120V, and has its own separate power cord.

I personally would probably either do it manually or use a relay.

Didn't/doesn't Swiftech make a ready to go relay kit? seems to me I had one on their relay kits (about five or six years ago) when I was driving a double rad setup with a Enhiem 120 volt pump.

here a link to what I was talking about, looks a little different from the one I had in the "olden days" Pump Relay Switch Kit v3
