I'm curious on what you use for the block, pump, and radiators. That looks like a nifty DIY liquid cooling setup.
The cooler I have is this,

It's actually kind of a hybrid AIO. The only one I know of (It's been years since I've checked the market though) with a built in reservoir with a strong pump. It comes as an AIO but they say you could actually use any tubing you wanted if you decide to expand it and go for more later since the pump can handle it. They sell fittings and stuff on the site but you don't even have to use theirs.
I figured it was an excellent starting point for me in case I decided to dabble in water cooling at some point. It's little brother was one of the best, if not flat out
the best AIO on the market but since it wasn't from a major manufacturer, it was sort of a hidden gem. I didn't even know about them until I was in the middle of seeking deals for my PC build and I think I read about them in somebodies post somewhere on a tech blog while I was doing research. I think it was overclockers. Learned that there was a new model on the way and I decided to wait a little longer, save up a little and not skimp on the cooling.
Oh, and thanks for asking, after looking up the site, I saw the replacement coolant and it reminded me I haven't even touched mine. Don't know if I need to top up or something... Should probably look into that

. But I've had mine for years now and it looks just as full as it always did...
