Recently got a quote for the following used server --

Dell R720 SFF
Dual E5-2670 8 core 2.5 Ghz
192 GB RAM
8x New Samsung 480GB SSD 
H710 integrated LSI SAS RAID 0-6
16 drive Bay server
Dual 750W power supply
Rail kit
1 year warranty

Quoted price was $2629/ea. The plan would be to replace my aging R905 with two newer servers.

Comments or suggestions?

Waiting for grandchild #2 to be born.

Maybe use the new equipment in production and turn your existing production equipment into your test environment?

@scottalanmiller Thought maybe you had decided to pull the plug for good.
