Dual-port 100GbE PCI-E 4.0 network cards are now under $1300

More importantly, 10GbE cards are cheap as free on eBay. That + a Mikrotik CRS305-1G-4S+IN and some direct connect cables you can have a 10GbE network in your house for well under $300.

I picked up the 8 port version from Microtik and picked up a Mellanox ConnectX-2 of eBay which came with a pair of 10G SFP+ fiber modules. A 10 meter single mode LC fiber off Amazon was like $20.

As for the NAS, I snagged a Supermicro mini-ITX 8-core Xeon D (Broadwell era) board from eBay as well for like $400. It brings out the dual integrated 10G NICs on the Xeon D, a PCIe 3.0 x16 port, a 4 lane M.2 port, and 6x SATA ports, 4 slots for DDR4 ECC RDIMMs, and an ASPEED based IPMI. Adding 64 GiB of RDIMMs, 6x 10 TB WD drives, and 2x M.2 drives on a bifurcating riser made for a killer NAS and VM host (crammed inside a Fractal Node 304)

Can I run this on vanilla Cat5e or do I have to put in Cat6?

The cheap used 10Gb NICs and the switch mentioned use SFP+ ports rather than RJ45. 10GBASE-T SFP+ modules are expensive and power-hungry compared to direct-attach twinax cables or fiber + transceivers.

I had a flat CAT 6 cable and could only get 5GbE - upgraded to a normal cat 7 cable and got the 10GbE.

Cat5e usually works fine. For longer distances you will need the correct (cat6 or better) though.

That's what I just did! Been loving it!
