I want to build a rig for ETC, DGB, XMR. Thinking about getting a full ATX case and dual RX 470s using Ubuntu. Looking for a motherboard that I can fit the two cards in without using risers. Any suggestions?

If it's only going to be used as a mining rig, I would skip the case and build my own BBT open air mining frame below for about $40 out of two 8ft pieces of 1/8" x 3/4" angled aluminum, one 8 ft 1" x 3" piece of pine, one 4ft 1" x 2" piece of pine and #8 1/2" self-tapping screws or out of all wood if you want to save some money. The cards will run cooler and it will easier to add more cards later if you want to.

For a motherboard I would also go with a dedicated motherboard like the Biostar TB85 for the same reason. You can put one card in the 16X PCI-E slot and use a USB riser for the other card.

https://www.newegg.com/Product/Product.aspx?Item=N82E16813138436

6 GPU Frame (Dimension 21" W x 15 3/4"" D x 10 3/4" H):

Build Cuts:

For the Angled Aluminum:

-First 8ft (96") Angled Aluminum; .75 inch of waste

4x 15 3/4" cuts (63" use) (Case Depth)
3x 10 3/4" cuts (32.25" use) (Case Height)

-Second 8ft (96") Angled Aluminum; 1.25 inch of waste

4x 21" cuts (84" use) (Case Width)
1x 10 3/4" (10 3/4" use) (Case Height)

And for the wood:

-8ft 1x3 Pine (96"); 2 inch of waste:

6 cuts of 15 3/4" (94" use) (Case Bottom)

-4 ft 1x2 Pine (24" left over):

1 cut of 21" (21" use) (Card Bracket Support)

If you're not thinking about expanding it further than 2 then this one will work

https://m.newegg.com/products/N82E16813128988

If you are, both of these are going to work too

Thanks for the input. I am thinking about only going with 2, and wanted to avoid risers. wanted to use a case too to avoid dust getting in. A contact of mine recently built a rig and dust fried the mobo.

Appreciate the input once again.

Spiders, especially jumping spiders, are another concern of mine.

ahhhh the spidery phantom menace! wreaking mayhem across the land in a mobo near you, soon to be in theatres! lol

Seriously, I hadnt thought of those particular issues. I'll have to check into arthropod damage because down here in Texas we have all manner of splendid creepy crawly creatures. One in particular, the crazy ant, loves electronics or maybe electric boxes.

Thanks for bringing that to my attention because all I was thinking about was mining eth and staking Bitbean when I built my rigs.
