Just discovered on a site for the sale of used equipment. Someone added an additionnal nic to the location of the VGA connector.
So he bought this :

and connected it to the mini pcie connector inside.
Btw you can find a 2.5Gbps Nic for cheaper here :
and this is the result :
So if you have an old optiplex 3050, maybe you can give it a new life 
Very cool. I've seen another mod where someone created their own m.2 to PCI and added a 4 port card into their usff machine!
I'd like to do this mod but not sure I'd have the confidence to create my own port!
You can do the same with a Lenovo M720q - Lenovo M720Q Tiny Build Documentation and Guide, without any DIY mods.
Or get a Cyberoam CR/15/25/35/(W)ING, for $25 and up, unless you need the excessive CPU power.
While you might get lucky, you're betting on the mainboard power delivery and cooling system to cope with a that additional load. 1 (additional-) port, yes - 2, maybe (probably), 4 has seen other boards (futro) crumble and crash - even more so if you go beyond 1000BASE-T, don't get too greedy (unless you're willing to risk defeat and hardware damage).
Don't get me wrong, it might work out well - but doesn't need to, so be aware of the risks and how far you can go without doing Russian Roulette.
3 posts were split to a new topic: OpenWrt installation on Dell optiplex 3050 usff
would this work ? connected to the M.2 port :

it's not a M.2A but M.2 2280...so i guess it will be necessary to remove the nvme and use a sata disk.
This is great timing! I have been scouring and looking around to build my own x86 machine, and only realised after seeing this post I have a Dell 3060 Micro with an i5-8400t (upgraded myself from a i3-8100t, since I was using it for tinkering with VMs).
Don't mean to hijack the thread but I have a few questions:
Would doing this "mod" be enough for an asymetric gigabit connection (1000 down, 100 up)?
My plan/usage is to connect it to a PoE managed switch and get 2 ubiquiti AP (U6 pro and FlexHD).
Appreciate any insight and help.
of course ! the i5-8400t can handle way more !
In my (synthetic) testing, an ivy-bridge c1037u (which is significantly older/ slower than an i5-8500T) could handle 1 GBit/s wirespeed with sqm/cake easily.
Awesome, I will report back in about 15ish days once the NIC from aliexpress is here.
Hopefully, it's all smooth sailing!
