Prebuilt vs DIY NAS: the Canadian comparison
By Ryan Fournier · Reviewed by Claire Bergeron · Updated · Prices checked A prebuilt four-bay NAS (Synology, UGREEN) costs roughly CA$550 to CA$1,000 without drives and arrives finished with a polished app suite and vendor support. A DIY N100 build costs about CA$450 to CA$650 for more CPU and RAM headroom and standard, replaceable parts, but you assemble and maintain it. Buy prebuilt for a finished product; build for hardware per dollar and ECC/ZFS freedom.
Prebuilt vs DIY NAS, at a glance
| Prebuilt (Synology/UGREEN) | DIY (N100 build) | |
|---|---|---|
| Cost, no drives (CAD) | CA$550–1,000 | CA$450–650 |
| Setup effort | ~30 min, guided wizard | build + configure it yourself |
| Software / apps | polished (DSM, UGOS) | TrueNAS / Unraid / Linux |
| Support & warranty | whole-unit warranty + support | per-part warranty, self-support |
| CPU / RAM per dollar | less | more |
| ECC / ZFS freedom | limited (some Synology ECC) | full: your choice |
| Repairs | RMA the whole box | swap a part locally |
| Best for | most people | tinkerers, ECC/ZFS builders |
The verdict: which should you buy?
What you pay in Canada
Prebuilt four-bay units land around CA$550 to CA$1,000 without drives depending on brand and CPU: a UGREEN DXP4800 Plus or Synology DS925+ sit in that band. A comparable DIY N100 build is roughly CA$450 to CA$650. The DIY box usually gives you more CPU and RAM ceiling per dollar; the prebuilt gives you a finished appliance.
Add the same CMR drives to either: at larger capacities the drives dominate the total, so a CA$150 difference on the NAS itself is a footnote once you are buying four 16 TB drives.
What the prebuilt gives you
Time and support. A Synology runs its setup wizard and you are done; DSM's Photos, Drive and Surveillance Station apps are genuinely good and have no turnkey DIY equal. You get a warranty on the whole unit and a support line. For most households that convenience is worth the premium.
The catch to check first is the drive policy: Synology's 2025 restriction was reversed for hard drives in DSM 7.3, but always confirm the current rule for your model before buying; the per-model pages cover it.
What DIY gives you
Hardware per dollar, standard parts, and freedom of software: TrueNAS with ECC, Unraid with mixed drives, or plain Linux. Nothing is locked, and a failed part is a trip to Canada Computers, not an RMA of the whole box. The cost is your time to build and maintain it.
The clearest case for DIY is ECC ZFS: no consumer prebuilt in this class offers ECC on an expandable platform. If that matters to you, build. See the N100 build and the TrueNAS hardware guide.

Frequently asked questions
Is a DIY NAS cheaper than a Synology in Canada?
Usually a little, and with more CPU and RAM headroom for the money: an N100 build runs roughly CA$450–650 vs CA$550–1,000 for a prebuilt four-bay. But the prebuilt includes the app suite, support and warranty on the whole unit, which the DIY route does not.
Should a first-time buyer build or buy?
Buy. A prebuilt Synology or UGREEN gets you running in 30 minutes with polished apps. Build once you want ECC, ZFS, or simply enjoy the hardware.
