How to Choose the Best NAS Case?

Before selecting the NAS Case, try answering the following questions:

• 1. How many drives will you need? Consider current usage and future demand; mostly home users start with 4 to 8 bays.
• 2. What is the size of the motherboard? The number of NAS cases is made to fit a Mini-ITX or Micro-ATX board. Where Mini-ITX is easier to build around and more affordable, Micro-ATX has additional expansion slots.
• 3. Do you want Hot Swap? It will help you replace, remove, or connect even when the system remains in full functional mode.
• 4. Consider cooling and airflow as your drive runs 24/7. Search for the NAS Case with dedicated cooling fans and better airflow paths.
• 5. Noise level? Must be low, otherwise you will get irritated.
• 6. Size and form factor: where will it fit? Desk, closet, server rack? Mini-ITX fits anywhere. A 4U Rackmount Case is the most drive-intensive case (requires a server rack).

Lessons Learned from DIY NAS Builds

Below are a few mistakes builders mostly commit:

• Always buy one size larger bay case than your current needs to avoid future drawbacks.
• Must check backplane failure if there are any for the previous years.
• If you are using compact cases, you might need an SFX/SFX-L power supply, and it will cost more than a standard ATX unit.
• Failure to consider how to achieve tidy cable management. 6-8 SATA cables will fill up the NAS case. Better routing saves a lot of headaches.
• Ignoring CPU cooler height restrictions. Mini-ITX NAS cases allow only coolers that are 55-70mm tall. Before you purchase your CPU cooler, check this out.
• Keep in mind to opt for a quieter NAS Case if you share the place with other people.

Guide for Buying a NAS Case

Before buying a NAS case, blindly go through the checklist below to make an informed decision:

• Check the motherboard compatibility whether the case matches your board or not.
• Always verify which PSU type is required, SFX or ATX. SFX is costlier than ATX.
• Make sure to always purchase extra drives for future needs.
• If your requirement includes a hot swap, make sure all bays include a hot-swappable.
• Make plans for expansion cards. Count the PCIe slots in your machine if you need additional SATA ports (HBA card) or 10GbE NIC.
• Decide where it will sit before buying. For the bedroom, go for a quieter one. For the desk, get a compact case.
• Do a thorough budget review, consider RAM, CPU, drive, PSU, etc. With Case.
