Server upgrade, bit in a pickle

[RasmusDC]

i am a bit ... on the edge serverwise at the moment.. running 10gbit in the whole house now. and have a server running the usual suspects..

 

I don´t really have that high demands for the "power" of the server, it runs a minecraft server, and Plex 4K UHD streaming and transcoding which is the highest demand, but runs fileserver, and remote steam lib. also..  running cloud

 

it is running 8 HD´s and 4 NVME SSD´s, but here is the issues, i running out of PCI-Lanes, on my 4790k and older Z97 board, running the NVME SSD´s on PCI-X4 cards, also the 10gbit nic, and i have grown to love the 1GB/sec transfer speeds, that i get from NVM -  ( well get around 700-800Mb/sec at most, but close)

 

so i need something with the same power of the 4790k and with more lanes, and the cheapest solution seems to be 

 

1920x Threadripper, since it is EXTREMLY cheap, the only issue is that the Motherboards, are nearly the same price as new 3 gen threadripper boards, but the chip is cheap.. 

 

is this not the best option, i guess it should perform as my 4790k at least, just with more cores, i guess the 4790k has more single core performance, that might be an issue with the Plex server, but it has an EXTREME amount of PCI-Lanes. 

 

and want to kill 3 of my Hd´s keep my 4x8TB  N300 and my 12TB Ironwolf, and buy 2x1TB NVME more, so i am up to 6TB NVM storage. the 3 HD´s will then be repurposed as vault drives with 2 other drives from an older NAS, so i have somewhere for the MOST important files, away from my server.

 

Looked at 3800x / 3900x and guess it has the PCI 4.0 standard, so in reality it has a high bandwith between CPU and board, but the main issue for me is that none of the "PCI-E" expanders i have, has PCI 4.0 the LSI controllers runs the older PCI 2.0 simple because of cost and 2GB/sec where okay per controller.
