Hmm, looks interesting, might be something to consider, as I've lost hope in all other AIO pumps, but I don't really see the point if it would be almost as easy, and better to just make a full custom loop. Unless ofcourse the price of one of these is ~~100quid.
I don't think this one will cost 100. If Corsair dual rads don't cost that little, why do you think this one will? I think it'll be around 150-200. It's basically a pre-built custom loop...
corsair is overpriced for what it is (P.O.S), and does not even compare to custom/other AIO brand ... ok they have good result across the board (that all the other AIO reach most of the time) but they cost around 1.5 to 2 time the price of some contestant in their respective class.
The EK WB Predator even above 100 would be a right price ... it still use better quality material than Corsair
(since a custom loop cost a little more if you select all pieces separately and according to your need) AIO aren't really worth it anymore ... (unless semi DIY kit like the Triton or those from swiftech )unless it's for a cheap build and you take a Seidon 120V/M or any sub 70$ one (and for HTPC/compact build also ... )
for instance Raijintek Triton core + replacing the rad by a NexXxos ST30 cost me 120chf ~ but i have 350ml of coolant on comparison of the few milliliter of propylene glycol (iirc...) that a "normal" AIO hold
keeping the original rad ... well 78chf (not counting the fan as you can recycle the one you already have if you have some
the core is really nice ) now compare that to a H100i or even the GT variant (who are +/- 1-3° around) who cost 70chf more and even need fan replacement most of the time ... (corsair is worth it, for RAM and case but the rest ... is "meh"...)
that kit is interesting nonetheless, tho lack some advantage a custom loop has.
