Free Motherboard / Is it worth it?

[Mvard]

So I work in hotels, and long story short a guest left behind a motherboard for what appears to be a replacement part for a Dell Precision T5820 workstation (Based off of the Service tag for the pc on the invoice). Naturally he didn’t want it back and now I have it. The box came sealed in an anti static bag with a license key for Win10 home, an alcohol pad, and a syringe of thermal paste. 
 

Im thinking about possibly making a build out of this thing, but I can’t seem to find out much info about the board. 
 

Dell specs the T5820 with Xeon W chips on the 2066 socket. What’s interesting is the socket on this board says it’s a 2011-3. I’ve tried looking up the dell part number but I can’t seem to find this thing anywhere aside from some random processor benchmarks utilizing it. Its a weird dell form factor that seems to be close to an EATX in size. I’ve attached the part number sticker from dell. 
 

Anyone have any guidance on how to read / research Dell stuff? I’ve poked around on forums as well as the Dell site and 02KVM seems to be the part number, but haven’t had any luck researching. Do you think it’s worth making a build of it?

You may want to contact Dell support with an email and ask to clear up this discrepancy, but IMO the CPU spec is far more reliable, as that can be seen in task manager so it has to be much more certain for the customer. Since the workstation lists 2066 Xeons in its configuration options, I think it's safe to say the socket is really 2066

Hey man, free is free! 2011 V3 is a fairly good socket as well, This is a list of compatible CPU's. If you have the scratch, I would 100% make a build out of it.

Can we get a full picture of the motherboard? Looking it up by image reference we can figure out by example if it indeed is LGA2066. I believe Socket 2066 also used the X299 chipset so if it has that it's definitely LGA2066. Being a workstation though it may be C612 or some other. C612 is for LGA2011-V3 so there's a couple ways we can figure this out.

Here are a few shots. I appreciate the help!

I researched the motherboard. It uses the C422 chipset which is for LGA2066. They must have just re-used that plastic cover.

 

You have a bigger problem though. As far as I can see the 20+4 pin looks standard but the CPU uses a 10-pin which isn't standard. I can't say what the pin-out is unless we have a compatible PSU to check and if a normal 8-pin will do the job or not.

Thank you for pointing that out! Totally would have missed that. Probs some good ol' Dell proprietary bs. I found a spec page and I think it looks like the PSU is hot swapable - which probably points to the odd connector. Might have to dig around to look for an OEM case & replacement psu for this thing. Feels like this could get real pricey real quick.

I mean, it's a free motherboard so you don't have anything to lose by learning the pin-out and just making your own 8 to 10-pin adapter then using a standard PSU. Need to do research on the proper PSU first.

Very True. I've been itching to build something. I've had thoughts on a media server / streaming rig. This is probably that push, if anything -- it came with a free key for Win10 so why not lol

All 5 pins against the top RAM slot are +12V

All 5 pins against the edge of the board are GND

 

So you could buy a couple CPU 8-pin extensions, butcher them, do some soldering & BAM you should be good to go assuming the 24-pin is standard.

Could you please let me know where you found that information? I have a T7810 and considering swap the mo but keep the psu - and I need to find out how to power the standard atx mo with 8-pin cpu socket with a 10-pin output from the psu. If this 5820 mo is the same with my 7810, I simply need to find a regular 8pin to connect to the 10pin output on the psu and that will work

Even though the motherboard uses a non-standard 10-pin a pretty easy google image search shows that the PSU follows standard color codes.

 

+12V = yellow

GND = black

 

If you really wanted to if you can source a standard EPS12V 8-pin you could remove the pins themselves from the 10-pin. Put them in the 8-pin then tape off the extra 2. Then you'd have a standard EPS12V 8 pin on the non standard PSU. As far as I can tell the metal pins look standard. Should work.
