EM-CASE-R turns the motherboard around. I/O, expansion slots, PSU inlet, power and USB all face the cold aisle. No rear panel, no side walls: a floor tray, a front panel and two ears.
The tray is open at the back. Long cards and cables overhang it.
Three heights × three depths, from 28 laser-cut parts.
Electrogalvanised DC01+ZE, rust-free indoors with no paint.
The 4U version also prints in PETG on a 256 mm bed.
Most rack cases copy the tower case: I/O at the back, a closed lid, cables in the hot aisle. EM-CASE-R treats a rack slot like a test bench. The board faces you, the top is mostly open and the back is not there at all.
The board is turned 180°. I/O shield, expansion slots, PSU inlet and switch, two 16 mm buttons and two USB-A ports all face you. Service the machine from the cold aisle.
A floor tray, a front panel and two ears. Nothing at the back, so cards and cables can overhang the tray and air moves freely.
Standoff holes for every board size are cut. You press studs only where your board needs them. ATX takes 4U; mATX and ITX fit every height.
Seven full-height slots in 4U, four full-height in 3U, four low-profile in 2U. The 4U card shelf adjusts ±3.8 mm to suit your bracket.
1.2 mm electrogalvanised steel for every part except the 2 mm ears. Four parts make a 2U build and eight make a 4U. Fold, rivet, done.
The 4U layout also exists as 11 PETG pieces sized for a 256 mm bed. The ears and side walls print as one piece, so rack load never crosses a joint.
The 4U layout comes in two builds. The steel version goes to a laser shop as flat cut files. The printed version is 11 PETG pieces at the same coordinates, so the board, I/O, slots and drives land in the same place.
EM-CASE-R is being prepared for its first production run. Preorders open soon, for the sheet-metal models and for the printable 4U. Follow along to hear the moment they do.
Every model, in the browser. Switch the hardware off to see the bare tray, or open the side rails on the deeper versions.
