A machined aluminium 1U rack panel on a steel workbench beside a caliper, a deburring tool and a circuit board. Behind it, a server rack with yellow fibre cables.

Bare metal.Both kinds.

Redimaker designs and machines computer hardware, then hosts it. Six services from one company in Redmond, Washington.

Fig. 1 1U front panel, as machined

We lay out circuit boards, print and mill the parts around them, design the rack hardware they mount in, and host the finished machines.

Use one of those services or all six. The list below runs in the order a machine gets built.

PCB design

A small green circuit board clamped in a metal holder on a grey bench mat, with tweezers, a soldering iron stand, solder and a printed schematic marked up in pencil. — **Fig. 2** Board in the holder, schematic on the bench

Schematic capture and board layout, taken as far as fabrication files. Boards are laid out against the mechanical parts they mount to, so the connectors land where the panel cut-outs are.

BringA block diagram, a schematic, or an existing board that needs changing.

Ask about PCB design

An enclosed 3D printer part-way through printing a black bracket. On the bench beside it are earlier versions of the same bracket, one snapped, and a spool of black filament. — **Fig. 3** One bracket, five versions in

3D
printing

Printed parts for fit checks, fixtures, cable guides and short runs. A printed part in the hand settles questions a drawing leaves open, and it is usually the cheapest mistake you can make.

BringA CAD model, or the part you need another one of.

Op 30

CNC milling

Parts milled from solid metal: brackets, rails, panels, heat spreaders. Prototypes and one-offs are normal work here, and the first part off the machine gets measured before the second one is cut.

BringA drawing or a STEP file. A dimensioned sketch will do to start the conversation.

A heap of curled aluminium chips and drops of coolant on a steel machine table. — **Fig. 4, 5** End of the cycle, and the other thing milling produces

Op 40

Rack hardwarePrototyping and design

Chassis, trays, rails, ears, and the odd parts that hold a machine in a rack. We design them, build a prototype, and put it in a rack to see what we got wrong.

BringThe thing that has to fit, or its dimensions, and the rack it has to fit in.

Ask about rack hardware

Two hands sliding an unpainted sheet-metal 2U server chassis into a black equipment rack. Pencil layout lines are still on the metal. A tape measure and a cordless driver sit on top of the rack. — **Fig. 6** Test fit of a 2U prototype

Fig. 7 19-inch rack mounting, EIA-310. Every prototype starts from these numbers.

The rear of a row of open server cabinets: bundles of yellow fibre and orange patch cords tied with straps, black power cords, a cable tray overhead, a step ladder and a box of spare cables in the aisle.

Op 50

Hosting

Rack space, power and network for machines that have to stay on. Tell us what you are running and how much power it draws, and we will tell you where it fits.

BringA parts list, a power figure, or just a description of the job.

AI

A GPU server pulled out of a rack on its rails with the lid off, showing a row of black accelerator cards and memory. A hand tightens a bracket with a screwdriver under a clamp lamp. — **Fig. 9** GPU chassis on its rails, lid off

GPU servers for training and inference, running in our racks. Dense, hot hardware is a mechanical problem as much as a computing one, which is why it sits on the same list as the milling machine.

BringThe model or the workload, and how long you need it to run.
