The pump works, although it seems to heavily rely on gravity to get water. It doesn't suck water if the water level is below it. I'd post a picture of the ghetto setup I did to get it all to work, but the sink is absolutely disgusting and I don't need the world seeing it. I used this ghetto setup to then flush out the radiator with hot water.
Installed the PSU into my case only to realize that I'm going to need to cut the hole for the PSU wires much larger since this PSU is longer. Apparently it's going to rain tomorrow though so I won't be able to do that

Probably setup my PC on my desk tomorrow though so I can cut the case eventually.
Basically just waiting for my Performance-PCs order now...
