That company appears to use good components in their products, so the servers themselves should be fine.
Before you talk to them or buy anything, you should determine your requirements, i.e., the number of users, how you plan to use the server (file sharing, backups, streaming, etc) as these sorts of factors will affect your CPU selection, amount of main memory needed, and amount and type of storage (SSD and HDDs).
You should also have a budget in mind as well. Also, your home use requirements could vary greatly from your office needs. In fact, many home servers are really older PC based rigs, re-purposed to serve a server.
If you layout some of your needs, folks here can help you determine what you should/should not purchase.
Good...
