Well just an update on the situation, I cancelled the order for a PA 120.3, and will be picking up a Feser Xchanger 360 from TerenceJ. Also from him I will pick up a Fuzion V2.
It's going to get a bit more restrictive with the fuzion V2, and I'm seriously thinking of either purchasing another pump for dual loop, or save the cash and go for single loop (probably wouldn't make much of a difference)
I also got the go-ahead for a new case next month..likely to be the HAF 932, but still needs to be decided
