Hi All. Here is the next system I am planning to build an enclosure from scratch. I want to cram in loads of water cooling capacity so I can really push the overclocking. While keeping the size down to a minimum. At 47 cm tall this is close to a mid tower size. Even with Aluminium and carbon fibre construction it is going to be heavy hence the high density title. CPU: Intel Core i7 8700K (delid ?) Motherboard: ASUS ROG STRIX Z370-E Memory: Corsair Dominator 16GB 3466MHz DDR4 RAM M.2 SSD: Samsung 250GB 960 Evo PCIe NVMe GPU: 2 x What I can get my hands on. PSU: Seasonic PRIME Ultra 850W Platinum Power Supply 1) Front Mount 280 x 60 radiator with 4x140 fans in push pull layout. Draw cool air in form the front. Cooling the CPU. Pump and Reservoir EK-XRES 140 REVO D5 PWM. 2) Bottom mounted 480 x 60 radiator with 8 x 120 mm fans in push pull layout Draw cool air in from bottom. Cooling 2xGTX TBD. Same Pump and Reservoir EK-XRES 140 REVO D5 PWM. I will try both serial and parallel cooling of the GPU's The whole enclosure could be shorter if I changed this to a 360x60 or 420x60 4) Power Supply moved to cover the motherboard where the rear fan would normally be. Aesthetics will suffer but I am really trying to stay away from full tower form factors. I'll add a second poll if I can. Should I have a vent in the side panel so the PSU can draw in cool air? Or should I have the PSU face the MOSFET heat sink to draw more air over that area. 5) Are 60 mm radiators an overkill?. Would it be better with 45 or 30 mm thick and a smaller enclosure? 6) Blue and Orange accent colour scheme for coolant and cable sleeving since they are complimentary.
