Used these as my homelab whilst doing my masters a few years ago. 
Have three servers total, these two listed are 96GB and don't have an onboard RAID card but check my other listing for the 192GB one.

Getting on in years a little but still very solid units and tonnes of RAM.

No hard drives included, when in production they used fibre channel, in my home lab I'm still using the HDDs in a slimmed down system.
The caddies are blanking plates but you can mount drives easily to them with a bit of handy work, and double sided tape for SSDs!

Has network management with CIMC which still works well and very handy to power up the systems remotely.
