About This Build

A living-room-friendly SFF build that disappears into a media console. The 4070 SUPER handles 1440p maxed and 4K with DLSS, and a thick low-profile cooler keeps the 7800X3D under control without sounding like a hairdryer. Cable management in a 13L case is a rite of passage.

Build journal

Written by the owner of Silent Mini-ITX 4070 SUPER as they built it. Any numbers below are their own measurements, not ours — each one says so, and says how it was taken.

  1. Build step 1Parts snapshot v1 — backfill: initial capture (PLA-3236)August 7, 2026

    Fitting the NH-L12S under the NR200P MAX side panel

    The tight part of this build is not the GPU, it is the 120 mm of cooler height the NR200P MAX gives you with the solid side panel on. The NH-L12S ships in two orientations: fan on top of the fins (taller, better airflow) and fan underneath, blowing up through them. Only the second one clears here. Fit the cooler before the motherboard goes in the case. Flipping the fan afterwards means pulling the board again, and in 13 litres there is nowhere to put it down. The SF750 comes with the case in the MAX variant, so the PSU line in the parts list is what you would pay buying the two separately. Route the 12VHPWR adapter behind the tray before seating the GPU — there is no slack to fix it later.
