Hi @Jake Lo,
Thanks for the advice. As you said, the DW1560 is slightly less expensive than the DW1830. I started doing some research on the card and the other NGFF/M.2 on the list. After doing a little digging, I found the following:
DW1560 has a Broadcom BCM94352Z chipset and seems to be identical to the Lenovo 04X6020, which can be found for around $20.
DW1707 has a Qualcomm Atheros QCA9565 chipset and seems to be identical to the Lenovo 04X6022, which go for around $6
DW1802 has a Qualcomm Atheros QCNFA222 chipset and seems to be identical to the Lenovo 00JT477, which go for around $5
DW1820A has a Broadcom BCM94350ZAE chipset and seems to be identical to the Lenovo 00JT494 , which go for around $10
Sadly, the DW1830 doesn't seem to have a Lenovo, (or any other manufacturers), equivalent.
I'm going to order the Lenovo 00JT494 and see if it works. I'll post up my results.
