Hi everyone! I want to turn my Dell OptiPlex Micro Plus 7010 into a Dell Precision 3260 Compact! So, I’m calling on Dell Precision 3260 Compact owners—I need your help!

Soldering the SATA 0 connector wasn't hard!

Soldering in the x8 connector—easy!

And that's when the trouble started! The device wasn't being detected, so I started analyzing the motherboard. Here is what I’ve found and what I know so far:

PRSNT1# – hard-wired to ground.

PRSNT2# (B17/B31/B48) – 3.3V; when the device is inserted, these pins are pulled to ground!

CLKREQ# – always 0; it's simply missing!

WAKE# – 3.3V.

PERST# – I got the correct signal by soldering in the chip and the supporting circuitry, including a capacitor for the 100ms delay.

PWRBRK# – ?

TX lines – filter capacitors are needed!

I need any help or tips! I don't have the original riser; I was working from photos! But logically speaking, there's nothing special about it other than stepping down 19.6V to 12V!

Hello everyone! I am an engineer not only by profession but also by heart, many things that fall into my hands become a little better or completely different! What am I talking about, some time ago I came across a Dell Optiplex micro plus 7010 at a local auction, and until the auction started I had time to prepare from the technical side - the PC was not working and according to the seller, it was giving post signals! I bought it for 60 dollars! While the PC was on its way to me, I found a processor according to my budget - Intel Core i5-13500t for 150 dollars (expensive to be honest, although I haven't bought RAM yet). Having received all the components, I started restoring the PC! Everything was not very easy, but everything works! After the work was restored, I started the upgrade - looking at the Dell Precision 3260 Compact motherboard - it became clear that the upgrade would be successful, even though all these unsoldered ports were in the device tree! The first thing I did was to unsolder the SATA - the capacitors that were smaller than the tip of a needle fell into place, I found the connector, unfortunately it was 16 pins, although Dell has 12! Hurray, the SATA is working! The next step will be to connect the video card via M.2-oculink, now we have one M.2 port and one unsoldered PCI! The plan is this

1st M.2 - Oculink video card

2nd M.2 - NVME M.2

Custom cooling of the processor and VRM zones

Print a case in sizes close to 3260 Compact (although the height will depend more on the type of cooling for the processor)

Unsolder PCIe 4.0 x8 and connect a 10Gbit network card there!

I found a riser for Dell Precision 3260 Compact in our open spaces but they ask for 70 dollars for it - I'm not ready to pay how much, not knowing - will it work or not!

I have a question, maybe someone has encountered such a PCIe upgrade on such PCs, or maybe someone knows what's in that riser! I would be glad for help! Because my head will explode while I look through all these lines and understand how it activates the connector!
