Putting It All Together
The motherboard tray and radiator panel fit into tabs integrated into the legs of the base, held in place with acrylic clips through slots in the upper portion of the tabs. This mechanism locks the motherboard tray and radiator panel in place. Both the motherboard tray and the radiator panel are angled when fit in place, along the plane of the body's legs. A tab in the top of the radiator panel fits into a slot in the upper portion of the motherboard tray to lock them in place and help to further stabilize the assembly (preventing side to side sway). The kit is shown with the option 4-fan radiator panel installed which we chose to use for our test bench build. The 3-fan radiator panel fits onto the rear side of the base in the same manner.
Both the motherboard tray and the radiator panel span the entire width of the body assembly, masking the innards of the kit and giving the entire kit a clean appearance. Both acrylic pieces mesh tightly together and with the constructed body piece for a solid design.
The true strength of Primochill's design is in the Wet Bench's configurability. The radiator fits on top of the radiator panel, held to the panel with screws through the panel into the radiator body. The angle of the radiator back panel allows for use of any thickness radiator and avoids any space contention issues between the radiator and the motherboard when mounted. The reservoir and pump can be mounted to the side of the legs on the body (as shown) or can be mounted to the body's middle tray if desired. Both locations have a multitude of mounting points for mounting accessories in any desired orientation.
Using the 4-fan radiator panel with a 480mm radiator proved a bit of a challenge to me because of the size of the radiator and the space allocated in the kit because of the tabs used to fix the panel in place. I could not direct mount the radiator to the place because of its size – the top and bottom chambers rested on top of the tabs, causing warping of the panel when mounted. The radiator was mountable without issue using the quad-fan radiator panel by placing fans between the surface of the panel and radiator. The fans provided sufficient space for the radiator's upper and lower collection chambers to clear the kits mounting tabs. This issue occurred because of the choice of using a quad fan radiator with this kit. If you using a 3-fan radiator with the default radiator panel provided with the kit, you should not encounter this issue.
For pump mounting, we chose to mount the pump along the inside of the right leg and underneath the middle tray, held fast through the provided T-shaped mounting slots. The pump is held in place using hardware provided with the fan as well as double sided, padded sticky tape. Rubber washers and padded sticky tape were used in mounting to prevent damage to the surface of the acrylic and to help eliminate pump vibration and noise.
The reservoir was mounted along the outside upper back of the right leg, mounted to sit parallel to the radiator panel. The mounting holes did not quite match up with those one the reservoir's support bracket, requiring the use of padded, double-sided sticky tape to hold it in place. However, the reservoir assembly fits very well in its location. Further, its placement takes it out of the plane of the motherboard tray, avoiding any potential space conflicts.
With the motherboard mounted and all water tubing connected, you can better visualize the genius in the Wet Bench's design. Even with an E-ATX form factor board installed, the size of the motherboard tray dwarfs the board. Their is more than sufficient space provided along all sides of the board to accommodate cable routing through the chamber underneath the motherboard tray as well as use of the motherboard tray's accessory plates. The system is shown with power and reset buttons in the accessory panel to the left of the motherboard and with quick connect barbs installed to the right of the board.
From the back view, you can see how the motherboard sits above the surface of the motherboard tray and the PCIe card bracket, negating the possibility of the board shorting or damage because of components on the back of the board getting crushed.
***UPDATE – January 30, 2015*** After getting many queries from readers asking about more details on the full system build using the Primochill Wet Bench, we decided to add some additional pictures of the final build for your enjoyment.
Full System Build
The base bench features a 480mm rad with six fans, outside mounted XSPC reservoir, inside mounted D5 pump, Koolance quick-connects between the tubing from the main system and the CPU block, as well as dual vandal switches on to the side of the motherboard for system power and reset functions.
The system PSU sits directly underneath the front right side of the enclosure, directly in front of the water loop's pump, with the optical drive and 1TB WD Black storage drive on the button left. The Intel 730 SSD used for the OS sits in the front middle, direct mounted to the enclosure's mid-tier tray. The PSU is not mounted to the enclosure, sitting on the desk surface just under the enclosure's mid-tier tray.
The XSPC Photon reservoir and D5 pump are directly mounted to the right side panel of the enclosure. The pump sits along the outside upper back of the panel, while the pump is mounted to the inside back of the panel. Both are held fast with screws through pre-cut holes in the panel. The Koolance quick-connects are mounted directly to one of the motherboard accessory plates with compression barbs on the bottom side of the panel and the quick-connect barbs on the top. The tubing is routed so that the reservoir and radiator can be disconnected from the system with little fuss.
The 480mm XSPC radiator is mounted to the radiator panel along the upper back of the enclosure with two front fans holding it to the panel and four back fans for added exhaust. All fans are hooked into a Swiftech fan controller mounted to the middle back of the enclosures mid-tier tray. The pump lies to the lower left of the radiator (when looking at the enclosure from the back. The pump inlet is direct fed from the side mounted reservoir while the outlet feeds into the radiator. THe radiator's outlet feeds into a quick-connect barb mounted the accessory plate on the motherboard tray.
The left side of the enclosure was not used for mounting hardware because of the proximity of the CPU block to the right side of the enclosure. The vandal switches along the middle left side of the motherboard tray are direct mounted to an accessory plate. The upper switch is connected to the motherboard's reset jumper while the lower switch is connected to the motherboard power jumper.
