I'm building a 12 bay media / backup system, tentative parts below. It seems supermicro is a solid choice, so I perused their selection of 2U cases and it looks like most of the 12 bays are under the SC826 model. I have a few questions that I would like some help with:
1. Some of the cases list "SAS3 12Gb/s 1x Expander" - Is this something I want or no? Previously I assumed a 12 bay backplane would just have 3 mini sas connectors (2 I will plug into an hba card and the remaining 4 drives using a reverse breakout) - but these cases say they have 4 mini sas connectors, what's that about?
2. With regards to my tentative parts list below - would 750/800 watts be recommended for my build?
3. This listing appears to be the SC826TQ-R800LP and has dual 800W PSU, what do you guys think? If you don't think that case is best, what would you go for?
Here's my wattage calculation for a fully loaded case (minus case fans):
Thanks!
