I'm going to need a few new physical servers running Ubuntu Server (12.04 LTS then upgrading next year to 14.04 LTS), and I'm wondering what is the difference between choosing a server from the 'Ubuntu Server certified hardware' list ( vs building my own?

I understand the need for hardware certification for laptops or desktops, where things like hibernate/suspend, WiFi, video card, etc are important. But what's the need for server certification? And what risks are there (in terms of compatibility with Ubuntu Server) with building my own physical server vs choosing an Ubuntu-certified server?

(I understand that when building my own servers I won't have a warranty, but that's fine because the servers are not for mission-critical use. I can handle downtime in order to replace any failed components.)

well each of the components will have warrany instead of the computer as a whole... – Alvar Aug 19 '13 at 10:58
So far I only had problems with BIOS in some older Cisco board resulting in no poweroff (had to force it by holding the power button down), easily fixed by a BIOS upgrade. Otherwise perhaps really exotic hardware may cause instability, or there are drivers missing, apart from that you should be fine with custom-build machines. – moon.musick Aug 19 '13 at 11:57
