This Listing is for (1) ONE Dell OEMR XL R520 Xeon E5-2407 2.2Ghz 6 GB DDR3 Perc H710 Mini

The first three photos are a representation of the server you will get
They are all in very similar condition from handling
There are are no dents or abrasions cracks or rust
The rest of the photos are from the IDRAC overview of each one

sudo inxi system display follows at the end with a description of methods used

Linux Mint sudo inxi -F -m -s
-F, --full           Full output. Includes all Upper Case line letters except -W, plus -s and -n. Does not show extra verbose  options such as -d -f -i -l -m -o -p -r -t -u -x, unless specified.

-m, --memory         Memory (RAM) data. Requires root. Numbers of devices (slots) supported and individual memory devices (sticks of memory etc). For devices, shows device locator, size, speed, type (e.g. DDR3). If neither -I  nor -tm are selected, also shows RAM used/total.

-s, --sensors        Sensors output (if sensors installed/configured): mobo/CPU/GPU temp; detected fan speeds. GPU temp only for Fglrx/Nvidia drivers. Nvidia shows screen number for > 1 screen. IPMI sensors if present.
