Take a look at the offerings at pogolinux.com You may find it is cheaper, in the long run and your time, to buy a pre-built system and if not you can at least see what they feel comfortable offering. Several years ago I ordered a system but wanted it with the latest version of a SCSI RAID host controller (with battery backup - if memory serves me right). Before I could get a quote out of them their engineers acquired and tested the card to make sure it would play well with the rest of the system.
