Since you'll want an off-site backup solution anyway in case of disaster, why bother paying for an expensive server that only reduces the chance of needing to restore from backup from 0.001% to 0.00001%? Flipping it around: what's the point of backing up to a remote server if the data you're backing up is itself corrupted? I don't think most of the upgrades you mentioned are really in the same bucket as ECC DRAM because only the ECC DRAM seems likely to prevent data corruption. Failing drives and cables and power loss, even failures that corrupt data, should be survivable events assuming drive redundancy, particularly given a filesystem like ZFS that will detect and repair the corruption.
