Working on a custom system that will likely live in a custom case. This is a personal project, a case design for my needs, so some of the choices may seem strange to some. The case concept is simple: ITX Mobo, ITX GPU, SFX PSU, 140mm EK-MLC Phoenix Radiator core in the front, around or under 10L. To help me bring this to light I have been chatting to the guys at PC Design Foundry who are a relatively new player in the custom case fabrication game and they've been extremely quick and responsive in helping me kick start this project. To see some more of their work either check out their website above or check out diceboii13's expandable case concept here. The system will use an EK-MLC Phoenix 140 core radiator/pump/res combo and a CPU block for my 9700K and will be pretty close to each other. Because it's such a short loop and only has 4 inlet/outlets I was thinking about consturcting the entire loop using angle fittings and solid extenders, but I was wondering if there were any particular issues doing this? I mean from my perspective this could almost aid cooling since air would move across the tubes and dissipate any heat they draw from the coolant, but because I have never done a loop with no actual tubing before I didn't know if I was walking into a bit of a trap. Anyone done this or at least loops with large amount of fixed fittings and extenders making up a large portion of the loop?
