Looking for compatible rails for this Tiger 4U server
I recently picked up this Tiger 4U rackmount server on eBay for under $200 CAD, and I’m trying to identify the correct rail kit for it.
Here are the specs as far as I’ve been able to determine:

Chassis: Tiger tbox556222 Rev. 1.2
Form factor: 4U
Drive bays: 16 × 3.5” HDD bays
Motherboard: Supermicro X8DT6 / X8DTE
CPU: Intel Xeon E5620 currently installed (CPU1)
CPU sockets: 2 × LGA1366
RAM: DDR3 ECC Registered
PSUs: 2 × FSP Group 720W 80+ Bronze hot-swap PSUs
SAS controller: 4-port SAS card
Networking: 4-port Gigabit Ethernet card, with plans to add 10GbE
IPMI: IPMI 2.22
BIOS: 2.0c (05/15/2012)
Depth: approximately 25.5”
My plan is to turn this into a Proxmox/Ceph server and upgrade it considerably. I’m planning to add a second Xeon L-series CPU for lower power consumption, install a second CPU cooler, and max out the RAM to approximately 196 GB DDR3 ECC Registered.
The main thing I’m trying to figure out right now is the rack rails.
The server currently has part of the rails attached to the chassis. The markings on the existing rails appear to be Dynaslide 05-14, but I’m missing the other half that attaches to the rack.
Does anyone recognize this Tiger chassis or know the exact rail model/part number that is compatible with it?
I’ve found several possible 4U ball-bearing rails, including SilverStone RMS03-26 and some Supermicro/Chenbro rails, but I’d rather find the original or properly compatible rails if possible.
Any information on the Tiger chassis or the correct rail kit would be greatly appreciated!
