We need to build a new web server for our organization. We have around 100 hundred small traffic web sites, so our hardware requirements are not too tough. We run CentOS 6, Varnish+Apache, PHP, MySQL, Typo3 CMS for most of websites.

Here's a hardware we want to buy:

• SuperMicro X9SCA-F-O (we need to have a remote management capability) (or better X9SCM-F?)
• Intel Xeon E3-1220 v2
• 2*4Gb DDR-III 1600MHz Kingston ECC (KVR16E11/4) (currently we have 4gb, and it feels like enough, so no reason for 16gb yet).
• Procase EB140-B-0 (1 unit)
• PSU 350W Procase MG1350, Active PFC

We already have:

• Intel 335 120GB SSD (for OS, databases and important websites).
• 2*2tb WD Green RAID1 (for other data and backups).

Does it look like a reasonable choice for our needs? Any issues with hardware compatibility? Any other notes?
