CaseLab case Mercury S8 current setup
After pouring through a lot of S8 builds, I noticed the space while it's much roomier than standard cases, it is still quite cramped for my ideal build.

I'll probably need to change the Top Cover: Ventilated, to Top Cover: Ventilated 36mm version Done!
Pedestal might need to change one side to use 120.2 drop in, instead of 120.3 drop in, to accommodate the RAID cage not happening, if it doesn't fit the RAID cage goes bye bye.
The small space in front of the PSU is probably not enough to install 2x EK D5 pumps. if a fan/radiator (36mm) is located in the front Flex slot.
A possible alternative is to hang the EK D5 pumps behind the 240mm EK radiator, each D5 in an EK 120mm bracket
Have the RAID cage on the first 120mm slot, hopefully not obstructing the 360mm EK rad on top (36mm drop from Top Chassis Mount)
if this doesn't work, then it'll have to go down to the Pedestal's Flex Slot, which will minimize require a separate 120.2 mount to install the 240mm EK XE Dual instead of the 360 EK XE Triple
or... get a 2nd Pedestal
... if that were to happen, I'll rather get a 2nd Mercury 8 to stack them up2nd Mercury S8 vs. Two Pedestal
- visually more attractive
- more windows
- much more space for pumps and reservoirs, plenty of room to create something neat.
- 2nd dedicated PSU to run all the water stuff, or have another 360 EK PE on the right side
- 360 EK PE on the left side
- perhaps even room for 2x 360 EX EX on the top, <--- needs to double check.
- more Flex Slots to install a 2nd RAID Cage, and Status Bays
- Possibility to install another 360 EK EX rad in the front.
- or possibly switch to 2x 240mm in the front.
hmm... Definitely something to consider 
not possible, confirmed by CaseLab, the MS8 was not designed to be stacked on top of each other, only Pedestals can be stacked.
Other data:
Mid width is 150mm to 160mm depending if you count the little bit of space on both sides
and length is roughly 200mm
