Hey all, I'm currently rocking a TR1950X + GTX 1080 and the system is starting to show it's age in gaming, so I'm going to build a new pc. I wanted to go ITX with this one, but i wasn't able to find the perfect case, so I decided to build one myself. The case is heavily inspired by the NZXT H1 and the Corsair One, but since you can't buy the latter one as a case, I had to improvise here. The case is minimalist with thick outer aluminium panels (4mm), dual mesh sides for the rads and a glass front. Everything is relatively square with only few round corners. As you all know the current situation regarding the availability of pc components is very dire, so I expect the full build to take multiple weeks or even months, as I need some very specific hardware for the components to (physically) fit my case design. Core components: Ryzen 9 3900X/3950X AsRock X570 Phantom Gaming-ITX/TB3 Nvidia GeForce RTX 3080 FE 2x 16GB RAM (probably 3600 CL 18 G.Skill Trident Z Neo RGB) SFX-L PSU (not sure yet which model I opt for) Keeping my old SSDs Dual 280x30mm rads from Alphacool BitsPower Monoblock for MoBo Bykski block for GPU A couple Koolance low profile 90° fittings, rest from Alphacool Alphacool 1U DDC reservoir + Laing DDC Silverstone 180mm AirPenetrator Noctua NF-A12 to mod the PSU fan Cooling concept: The idea is quite simple, I only have two fans in my system: The PSU fan intaking from the side through part of one rad and exhausting to the back and the 180mm Silverstone AP on the top sucking air out of the case. I have designed the case to be completely sealed at the back (only cutouts for PSU and MoBo IO) and at the front (full tempered glass front). This means the air is forced to be sucked in through the mesh side panels and the dual 280mm rads which will not have fans installed. Additionally I will reinforce the mesh with a panel that will block the area around the rads so the air must always go through them. If you know the Corsair one this concept will be nothing new, and as I mentioned earlier this was the main inspiration for this case build. The GPU is rotated by 90° and mounted with a riser cable. I will use low profile extensions cables to reroute the DP connectors to the back of the case. Case components: I unfortunately have limited metal working tools available, especially no CNC or anything to bend sheet metal. Thus, I have designed the case to be built mainly by cutting the parts out of flat metal sheets, only the top has to be cnc milled by an external company. The exterior will be made out of thick 4mm Aluminium, which I will probably glassbead and anodize. The interior components will be cut out of 2mm steel sheets that I will paint and everything is mounted together with 3d printed mounts with metal inserts as well as M3 mounting cubes. The mesh side panel is made out of 1,5mm magnetic steel and will wrap around a 1mm steel insert resulting in 4mm thickness just as the aluminium parts. The side panels will be mounted with neodym magnets. The front is made out of tempered glass which I obviously also have to buy from an external company. I will put some black vinyl wrap on the back of the glass and then will glue some magnets on the wrap to secure the glass to the case. The thick bottom and and backplate in combination with the 2mm spine holding the MoBo should be strong enough to be a good starting point when assembling the build. Pictures: Progress #1: I have already ordered the lasercut Aluminium parts as well as the steel sheets. They should arrive soon for me to cut them into the correct shapes and add holes. I should also be able to spray paint the steel parts sometimes next week. I will probably have to wait until it's warmer to glassbead the aluminium parts. My air compressor is in the garage (it's massive with a 150l tank etc. so I can't move it inside) and unfortunately very reluctant to start at the current temperatures of -6°C. I will also have to order some of the watercooling blocks soon, as they might be shipped from China/Taiwan and take a couple weeks to arrive.
