**The full detailed building instructions are available in the included PDF, or [via this link to Printables.](https://www.printables.com/model/1536973-budget-friendly-compact-matx-case-with-atx-psu)**

**About the case:**
Unique looking Micro-ATX case designed specifically to be both budget-friendly and also be printable on small printers down to 180 x 180 x 180 mm in print volume. A perfect little project for your Original Prusa MINI+  or similar printer.

**Good to know:**
The case shown in the pictures is printed exclusively in Prusament colors. The main body is printed in Prusament PETG Prusa Galaxy Black 1kg while the side panel is printed using Prusa's two brand new PLA colors created in collaboration with Noctua. Check out the Prusament PLA Noctua Brown 1kg and Prusament PLA Noctua Beige 1kg. The total filament use is shown in the table further down.

**Overall case size incl. feet:** L:300mm H:295mm W:190mm (excl. headphone holder)

**Compatible components:**
 NOTE: Not all parts listed can fit at the same time, please plan your layout based on build video and presented layout pictures. Feel free to ask for help if needed, see Discord link further down.
- Micro-ATX or ITX motherboard
- ATX or SFX power supply
- Graphic cards up to 275mm - (250mm if using lower front HDD/fan mount)
- 120mm AIO Liquid cooler - (possible to do push+pull config)
- Using ATX PSU: CPU Cooler clearance 65mm (For ideal airflow < 55mm)
- Using SFX PSU: CPU Cooler clearance 85mm (For ideal airflow < 75mm)
- 3x 2.5" SSDs - (2x instead of front 120mm fans or 3.5" HDDs)
- 2x 3.5" HDDs - (instead of 2x 2.5" SSDs or 120mm front fans, requires the use of 90-degree SATA power and data cables, see comment two sections down regarding HDD use)
- Up to 4x 120mm computer fans - (2x front fans if not using 3.5" or 2.5" HDD/SSD in the front)

**Required parts to complete build:**
- 50x (approx.) M3 threaded inserts (M3 x 4.6 x 5.7 mm)
- 50x (approx.) M3 x 10 mm screws
- 16x 8 x 3 mm neodymium magnets
- 12 mm momentary push button (power button)

**Optional parts:**
- Front-panel mounted dual USB cable (see comment in next section)
- Super glue (to keep the magnets in place)

**Important considerations before building in this case:**
**IF YOU PLAN TO USE 3.5" HDDS:** If your motherboard has built in 90-degree SATA connectors pointing to the side, you may not be able to use a 3.5" HDD in the lower front slot depending on where the SATA ports are located. You can still use a 120mm fan or 2.5" drive in the slot, then just put the 3.5" hard drive in the upper slot. 

**IF YOU PLAN TO USE FRONT PANEL USB PORTS COMBINED WITH 120MM AIO:** Depending on where your 20-pin front-panel USB connector is located on your motherboard it may interfere with using a 120mm AIO. _(A low-profile USB header extension might solve this challenge)_

Budget-friendly mATX case

mATX_noctua_curvy_side_full_CAD_31DEC25_v1.step

**Key features:**
6 slide-in Latching Quick-Swap Hard Drive bays (3.5" HDDs up to 1 inch thick)
3 Additional 2.5" SSDs (System drive + dual cache SSD)
Full height single-slot PCIe card support (SATA card, Slim video card, Network card etc.)
Magnetic front-panel for super quick front access to the drives and cables.
Mini ITX Motherboard
SFX or SFX-L power supply
3.5" to 2.5" drive adapters available for main bay.

**Print volume required: **
210 x 210mm

**Case size:**
H: 341mm, W: 210mm, L: 217mm

**Materials/components required to build this case:**
31x M3 threaded inserts
31x M3x10mm machine screws
8x   8x3mm Neodymium magnets
1x   PC Screw kit (for standoffs + HDD mounts)

**PC Components required/recommended:**
Mini ITX Motherboard / NAS Motherboard (ITX form factor)
SFX or SFX-L Power supply
Single slot PCIe expansion card of your choice. (optional)
2x Slim 92mm PC fans (up to 22mm thick)
3.5" HDDs (Up to 6x)
2.5" SSDs (Up to 3x)
SATA power and SATA cables with 90 degree connectors (due to limited clearance)
12mm Power Button

**Designed with easy, clean cable management in mind. **

90 degree, flat/flexible SATA cables are recommended due to limited clearance to the front panel. The picture/layout shown above and in the video uses 3x 50 cm cables, and 5x 30 cm cables. One more cable is also required if you are using the last SSD drive mounted at the top of the case. (see video for reference)

Cable lengths stated above are just guidelines based on a similar setup to the one shown, and requirements may vary depending on your choice of parts.

**PRINTING INSTRUCTIONS:**
Minimum print volume required: 210 x 210mm
Recommended material: PETG, but ABS or ASA also works.
Recommended layer height: 0.2mm
Print speed: Not important, whatever is recommended for your printer.
Recommended wall thickness: >2mm (5 walls at 0.4mm width)
 
* All external panels (front,side,top,bottom,rear) are printed using only walls and infill (15-25% density). 

* All internal panels like the hard drive bay, motherboard mount and hard drive mounts should be printed normally with both top and bottom layers.

* All parts except for the top of the drive-bay are printed without supports. The one file that does need supports is clearly marked with the word “SUPPORT” in the file name. (Use custom painted supports just under the overhangs if you can, otherwise the threaded insert holes may be filled with supports that are difficult to remove)
