Joshua Kirman,  The R610 shouldn't have any issues with what you are trying to do. A. Does support using 8GB dimms (part # M9VK3)  B. Does support 1TB SATA (part # 50XV4) C. It does support using Server 2012 (link to pdf for supported OS's)  Let me know if this helps.
Greetings, I recently took over as consultant for a client with a PE T310 in a branch office that was used as a file server a few years ago, but has been sitting idle for c. 2 years.  S/T is 2TDBZV1, current specs are 4 GB (2 X 2 GB), 4 X 1 TB SATA HD, Perc 6/i controller, hot-swap drives  4 X 1 TB SATA 7200 drives.  It is running Linux.  I'm considering repurposing it with following specs and using as a backup Windows 2012 DC: a) replace memory with 32 GB RAM - 8 GB X 4 b) replace HD's with 2 X 1 TB SATA in RAID-1 config c) Install Windows 2012 Assuming it's not too expensive vs. buying a new unit outright, can this be done?  Thanks for your feedback.  jkirman
