1U Servers get very loud and are extremely limiting on options. Personally I wouldn't use anything smaller than a 2U. SuoerMicro do a 2U with up to 8 drives in the front, proper PSU redundancy etc, plus you can add a bigger amount of linecards X7 is quite old now too, and the CPU's are 10years old. DDR2 ECC is rare now, so replacing a failed component would be expensive. I doubt the X7 has SATA3, so limited to SATA2 which isn't an issue if only using spinners, but ssd would suffer. Honestly, for what you want, I'd look at a used Dell R710 LFF. Have you checked if the X7 board can handle 64bit LBA? Ie Drives > 2.2TB Just some thoughts to consider :-) Sent from my iPhone using Tapatalk
