12v, 8a. hmmmm, so many psu's provide like 12a on the 12v line, thats just cutting it too fine for so many people.
I'd also like to point out the 12v bilge pump thingee for this won't be an issue, as it isn't actually a bilge pump, it's just a really big 12v pump. It also doesn't look like a mag drive, and the site mentions a stainless steel shaft, This will mean seal issues over time, but it'll provide a ton of pressure. I'd like to know how reliable they are when pumping through restrictions of 1/2" tubing and waterblocks.
also I had to laugh at ''In the past with many pumps used in the water cooled PC market caustic fluids were not recommended, not true with the 1200 GPH unit. These pumps are designed for caustic fluid transfer under constant duty'' but I bet they'll still void the warrenty when they all die off and have been used with the water wetter they sell.
It needs a **** load of power, and is inline, so your case will have a ton of heat going into it. Of course if it was submersable their entire radiators wouldn't be able to handle the heat, so that mightn't be a good idea either
but it's $150!!!! You can buy a Danner 2400gph for that, or 2x 900gph Danners for that amount of money
