Well to be fair, the article only calls it an AIO ... and not all AIOs are CLCs, tho Deepcool's usually are. The Digital Storm one on the other hand isn't and you can expand it.
This one uses a Swiftech AIO, which are expandable

This looks so cool. Only in my opinion open loop for gpu would be better. Skylakes require so much less cooling than current gpu flagships. I dont see the point spending ~100$ on a cpu cooler anymore.
6700k = 95 watts
4970k = 88 watts
4770k = 84 watts
On the other hand ....
GTX 770 = 230 watts
GTX 970 = 145 watts
If anything, GPU TDPs are shrinking drastically, while CPUs are climbing slightly
The reason why CPus are far more often water cooled is twofold:
1. Overclocked, we quickly go beyond the capabilities of the stock CPU cooler such that overclocks are impacted. You hit the thermal wall before you hit the voltage wall. OTOH, as often as not, GFX cards will hit the voltage wall before the thermal one. My twin Asus780s run at 39C at a 26% OC. Shortly thereafter, did a MSI 780 build which got to a slightly higher (almost neglible but notably higher) OC and they were air cooled and peaked about 78C.
2. GFX card blocks are much, much larger and thereby can quickly remove heat from the GPU / VRM / VRAM due to the huge thermal mass of the block. Ob the CPU, we have the logjam of the small surface area where metal makes contact w/ water... and on air coolers, we have the logjam of moving the ehat from small block to limited size heatpipes, which then have to transfer the heat to the fins.
Run a CPU stress test like OCCT with stock cooling, even at stock settings, it will shut down within a minute due to the build in protection at the default setting of 85C, Run a GPU stress test at stock settings and nothing happens.
CPU air cooling will produce better results than CLCs, but of course a custom loop will eclipse both with rads properly sized. OTOH, if you are adding GPU water cooling to improve performance, having the GPU at 39C provides no advantage than having it at say 78C if it doesn't start throttling till it gets to 85C. Some cards will benefit from full cover water blocks but not from CLC or hybrid solutions because when performance limited by temps, it's usually because the VRM is too hot. However other air cooled cards, with superior thermal solutions and well designed PCBs (w/ beefier VRMs and thermal pads on VRM / VRAM) are unaffected.
