It’s a little confusing but the pump is on the left side of the gpu it uses the Alphacool Eisstation 40 DC-LT - reservoir and the Alphacool DC-LT 2600 Ultra low noise ceramic - 12V DC. And the case is the Formd t1Loop order does not matter as long as the pump doesn't start pulling air. Liquid cooling pumps can only pump liquids - they cannot pump air.
What case is that? It looks pretty crammed - also, looks like there isn't a reservoir, so that thing has to be 100% full of coolant - no air.
mITX and mATX full liquid cooled builds are what I like.
