O11 Evo or XL, if using the flat reservoir and the shallow DDC pump, can fit in the secondary chamber, where the PSU is.
Another option, but not cheap, is one of those radiators which includes the pump in one of the corners. Haven’t seen any for sale in the UK, was mainly from a German competitor.
Also, another expensive solution , the new EK waterblock which includes a pump and a tiny reservoir. Taller than the regular waterblock.
A more practical and not as expensive solution, but make sure you take the case’s measurements beforehand, using cross-flow radiators can help… a lot.
Also, if you decide to go with soft tubing, EK ZMT. Looks great is using only nickel fittings, then all acetal. Chrome and acetal, despite looking more discrete, does look more premium. Also acetal is more resistant than acrylic.
Or you could go with dark fittings too, or just use one of those rings (from EK, compatible with their last fittings) which can give you a chance for some subtle colour without going DFI Lanparty style.
Now, back to cases, the O11 is very popular, but is a show case.
If you want something different, some cases with a “basement” area big enough, can accommodate the pump, or even the Fractal design and its dual 5.25 can accommodate a (now) very rare bay reservoir.
The Lancool II can easily do dual 360, without complicating things.
But before all, do you have any space limitations?
I’m assuming you don’t want any thing that would say: doable but pulling the dremel out.
used quite a lot of cases, as it’s the thing that I change more often, too often.
Dual chamber can help to hide reservoir, pump, or even run some of the tubing at the back.
I would recommend the EL LT120 reservoir/pump. Personally I like the D5, but takes more space, and you can’t hide at the back of the O11 EVO for example, but if mounted on the side, the reservoir area won’t be as noticeable as the other tube/squarish reservoirs. Had one between two Phanteks T30 and looked fine.
