How to cut and fit J3455B ITX and INTEL ETHERNET i340-T4 on a Corsair 250D case

[lovan6]

I am new to this forum and decided to build Pfsense.

Parts:

Asrock J3455B ITX

INTEL ETHERNET i340-T4

40GB Intel SSD

4 GB DDR3 1600 sodimm

I need information what is the best way to fit the Intel card on the motherboard. I read somewhere in this forum that it involves cutting either the motherboard or the nic.

What is the best way to do it? The motherboard is brand new while the nic is used.

I am also open to suggestion on using a riser card if it fits on Corsair 250D but I have no idea what to buy.

Asrock J3455B ITX
Board = 1 PCIe 2.0 x16 (x2 mode)
INTEL ETHERNET i340-T4
PCIe Card = 1 PCIe 2.0 x4

So it should be able to stitch this card directly into the PCIe x16 slot for sure, without any hassle or
problems and it should be also be able to place it into that case as well too! So there is no need for a riser cable.

If the card is greater then the PCIe slot, it could be a work around, but in your case the slot is greater then
the PCIe card and this might be then no problem, insert the card into the slot and all will be fine for you.

Board into the case and card into the slot, that´s the way to go with.

Why do you think there will be a riser card or cable needed? Perhaps this card comes with a low profile bracket
or it is not matching to the slots of the case then for sure you will bee able to went to amazon.com and get the
right working tolls to walk around any problems. Here are shown some of them right to buy or go with.
