Build your own DIY 2011 v3 Dell Precision workstation.
I recently got a mobo+cpu from a Dell Precision T7910 for a very low cost at an electronics recycling shop. It’s perfect for handling many multithreaded tasks. I have ample ECC DDR4 RAM and two extra power supplies ready to go. I’m trying to determine if I can short some pins to get it working like a regular motherboard, or if I really need the special front panel connector to set it up as a power switch. I’ve worked with similar boards before, but this one has a large unlabeled front panel connector. Have anyone else modified Dell workstation mobos from this time? They look affordable. Right now I’m just trying to turn it on, and if you know anything about these 2011-v3 precision boards, any tips would be great.
There should be an adapter available that matches a PowerMac/Mac Pro front panel setup for standard ATX. If not, you'll need the original part. I've worked with similar projects (like my HP Proliant G6 on LGA 1366), which often involve unique solutions. Most of the time, HP and Dell are known for having proprietary components in the aftermarket. I’m excited about getting back into older server configurations—thanks for the reminder!
It was a quicker response than anticipated, which is disappointing since I can't just insert a screwdriver into one of these devices to activate it. It seems the cable I need is likely the one labeled 6W2X6. It's unclear if this applies only to the front I/O or if it also covers the power switch. The offset button aligns with the front panel design on the T7910 chassis, so maybe I should go ahead and order it, hoping it's correct. Seeing Dell and HP grouped together in the same category isn't ideal, especially since HP has had issues with proprietary memory options in their systems. Now I'm concerned that the additional 128GB of SK Hynix RAM might not be compatible with this board.
If I manage to bypass Dell's confusing specs, the whole setup should be around $500 for a 28c56t with two CPUs, 128GB DDR4, the motherboard, and the original PSU plus distribution board. I found some unused power supplies and plenty of ECC RAM nearby, which helped me secure the board at a discount since it had a damaged RAM slot—possibly still functional but unproven. I’m really hoping it will work.
This particular component isn't something I'm very familiar with. I understand SK Hynix is considered one of the least compatible memory suppliers, with Samsung and Micron leading the pack. Most server boards should be fine as long as they support ECC memory. Probably the right cable you're looking for, though in the worst case you might need to search for a compatible case or replace the entire system. Yeah, that's what can be frustrating with prebuilt units, especially in servers. There aren't many parts you can easily swap because everything is proprietary.
