NexGen3D: DIY Steam Machine - Phiên bản REDUX

Update: 2-04-2026

The REDUX Case is now available from multiple locations:

• My Web Store: https://nexgen3d.bigcartel.com/product/redux-steam-logo

• US Etsy: https://www.etsy.com/listing/4478601250/nexgen3d-diy-steam-machine-redux-edition

• UK Etsy: https://www.etsy.com/uk/listing/4477781391/bc-250-redux-steam-machine-case

I will add a few face plate and colour schemes over the next few days.

Update: 1-04-2026

• On request I've just uploaded some side covers without any logo's

Update: 30-03-2026

• I've uploaded newer versions of the fan mount, this was to address the false flag of the slicer saying supports were required.

• I've uploaded newer versions of the side panels and the vertical mount, I adjusted the M3 bolt counter sink depth, as the 10mm bolts only had a few mm of thread engagement. 

For those that have been busting at the seems for me to get this out the door, I'm pleased to announce my latest creation

The DIY Steam Machine - REDUX

I will be updating this list over the next few weeks, so some information is still missing, as I'm extremely busy at the moment, but I will get to it, most of the build guides from the previous case are the same, so you can refer to that for information: DIY Steam Machine 

Standout Features:

• Dual 120mm axial fans for higher thermal cooling performance.

• New full floating fan mounting system with:

  • Optimised for air flow and reduced back pressure.

  • Reduced fan noise.

  • Additional clearance from the finstack.

  • Can now be printed from PETG.

  • Integrated cable management.

• Enhanced hot air exhaust system:

  • Additional clearance between the stock heatsink and the case.

  • Air guides to enhance back plate cooling.

  • Room to add unnecessary additional heatsinks.

  • Room to add the optional rear clamping brace for enhanced heatsink clamping pressure.

  • Additional exhaust port for maximum air flow.

• Removable/Swappable face plates.

• Decreased noise generation from the upper hex cover.

• More compact and less material required for printing.

• New super cool looking vertical stand.

• Case available in multi-material, and non multi-material.

• Inter locking case for better seam alignment.

The only additional hardware this case requires over the original case, is an additional fan.

I recommend the Arctic P12 Pro CO with PST fans, but these are not a requirement, any pair of good quality fans will do the job, I find this new design, only needs to 40 to 50% fan speed to out perform my original case with the fan at 100%. (P12 Pro)

The Arctic fans are still my choice, but feel free to try what you have before shelling out for more fans as they may do the job.

Currently this is the initial release, I will be adding at a later date the following:

• Split upper and lower hex covers

• Server FLX PSU rear case

• Some additional face plate designs

Bill of Materials:

The BC-250: I have purchased 3 now from this seller, and many others have as well, so they seem reliable, and the pricing is about the lowest outside of the USA.

• BC-250 Single Board Computer

Power Supply: A few points here, the cheap low cost Flex ATX, are called all sorts of different names, but they are all pretty much the same thing, junk, but they do the job, the 400 and 500w units are okay, just make sure they are cheap, make sure to compare the pricing against the Metalfish 500w as the difference between the Metalfish, and these other low costs units is like night and day, my opinion, is try to push you budget to the 500w Metalfish, don't waste your money on a 600, or 700w, its just not needed, I have pushed the 500w with water cooling to the point where the plugs have melted, and the 500w has never gone into OCP, but the cheaps one have, and they have done this well under the 400w rated power, usually between 360 and 380w, and they get really hot, there efficiency is rubbish as well, if you are in the USA, then go straight to ebay and try and pick up an FSP500-30AS for around $15 to $20 USD, this is also a top notch PSU.

• [MetalFish 500w Flex ATX (Recommended)](https://)

• NoName ElCheapo 400w Flex ATX

• SKYWINDININTL ElCheapo 400w Flex ATX

• FSP500-30AS 500w Flex ATX
