Description

This is an update on an earlier build of mine which can be found here. https://pcpartpicker.com/b/4fTH99 I have provided details here on a modification I made to enhance the cable interface and airflow, as well as provided more pictures of the build. I hope this is helpful to 901 users and enjoyable for the rest of the community.

The Inwin 901 is a gorgeous case but has a peculiar setup for the rear IO that is not conducive to mobility or air flow. While the case was not meant to utilize 140mm fans, they ended up fitting very well with certain modifications. Unfortunately that still left the issues presented by the rear panel, in particular the rear fan grill and its proximity to the cable passthrough.

With the 140mm fan in place, space is at a premium for the rear cables, as there is not much clearance between the motherboard IO and the case fan housing. For this I made extensive use of right angle connectors to great effect. Additionally all the cables used are relatively short and have female terminations, so they lend a very modular capability. This is important as removing the rear panel is a bit of a pain as the cables need to pass through it. If you want to move the computer you would have to carefully remove the panel and unplug all cables. With this modular cable setup I implemented, you just need to disconnect the cables externally and there is no need to remove the rear panel.

The remaining modification served two purposes. I needed a way to have the cables exit in an aesthetically pleasing way, but additionally due to the proximity of the rear cable passthrough to the exhaust fan, I needed to seal the cable exit as best I could so as to maximize exhaust fan efficiency. A significant amount of waste occurs because the exhaust fan circulates fresh air through the cable pass through instead of solely venting hot air from inside the case. By creating an effective seal around the cables, overall case cooling should markedly improve.

A good amount of researching and trying different parts landed me on this effective solution. I used the innards of a wall brush plate as my cable exit. This is both good looking and seals pretty well around the cables. Secondly, I found a company that makes a suitable wall plate in both size and finish. A brushed stainless steel 2" slim plate was the closest match to the brushed aluminum of the case and just barely covers the factory passthrough. The finish is not a perfect match of course, but is still pretty slick. I wish I could say I used some fancy method of securing the brush plate assembly but after many attempts I found hot glue was effective and could be removed without any damage and with minimal hassle.

Some cable braiding on the exiting cables is a decent final touch.

The Inwin 901 understandably remains a popular choice as a reasonably well set up ITX case with fantastic aesthetics that has just a few quirks that present challenges in airflow and cable management. I believe the combination of modifications that allow circular 140mm fans, the low profile modular style cables, as well as the changes to the rear panel in enhancing looks and air cooling performance make this a more versatile and capable case. My hope is sharing these mods will help current and future 901 builders enhance their rigs. If you happen to implement any of these changes let me know, I'd love to hear how they went!

Thanks everyone!

EDIT: I tried to add links to all "Custom" parts but as far as I can tell they only show up when I'm logged in to edit my build and they aren't showing up for anyone else. You can easily find versions of most of the parts yourself, but the wall plate is a very specific part!

Thanks! Dang you found this repost quick. :p Hope your machine is still chugging along great. No complaints over here, other than the mess that accumulates on my desk and spoils the look.
