A disadvantage is that the total parts cost is often higher than an equivalent commercial-off-the-shelf product. I needed to replace my Debian 9 SOHO Samba/ CVS file server last year -- Intel D945GNT desktop board, 3.4 GHz Pentium D, 2 @ 1 GB memory modules (failed memory slot for 3rd or 4th memory module), single 3 TB desktop disc with ext4, and 1 Gigabit port. After much research and many delays, I bought a recent and lightly used Dell PowerEdge T30 for $375 on Craig's List. It came with a mini-tower case, single 290 W power supply, single rear cooling fan, half-height 5.25" DVD+-RW drive, 4 internal 3.5" drive bays, 1 @ 1 TB SATA drive, Intel Xeon E3-1225 v5 processor, 1 @ 8 GB ECC memory module, 4 SATA III ports, 1 PCIe x16 3.0 slot, 1 PCIe x16 3.0 slot (x4 speed), 1 PCIe x4 3.0 slot, 1 PCI slot, and 1 Gigabit port. I removed the 1 TB drive, added a second 8 GB ECC memory module (system supports 4 @ 16 GB), and installed 3 @ 1.5 TB SATA desktop drives. The goal was a SanDisk Ultra Fit 16 GB USB 3.0 flash drive as the system disc, encrypted swap, encrypted ZFS root, one large encrypted partition per SATA disc, and RAIDZ1 for data. I tried Debian 9 with contrib ZFS -- it ran for a while, then broken when I forced a kernel update. Then I tried FreeNAS, thinking it was FreeBSD with a nice web GUI on top -- I was wrong. Then I tried FreeBSD 11.2 -- success! This computer rocks, and should be overkill for years to come. The problem with having a computer with several discs in RAID is that you want another computer with several discs in RAID as a backup and maintenance mule for the first. So, I am currently rebuilding my old file server, keeping the ATX full-tower case, power supply, optical drive, and hot-swap bays. I found an Intel S1200V3RP motherboard with Intel E3-1225 v3 processor and 2 @ 4 GB ECC memory modules on eBay for US $110+. (I believe this motherboard has 6 SATA III ports and supports 32 GB ECC memory.) The motherboard also has an unusual 5-pin connector for communicating with the power supply; my power supply does not have the matching cable. If it works, it should be equivalent to a Dell PowerEdge T20. This approach may or may not work for you. In either case, if you plan to do disc encryption, be sure to get a processor with AES-NI. Ideally, one core per disc plus additional core(s) for everything else. You might get more/ better replies if you stated your workload/ applications/ services, number of concurrent users, compute requirements, RAM requirements, storage requirements, network requirements, etc., and the make/ model of parts you plan to re-use.
