Any recommendations?

I'll send 0.25BTC to the person posting the one I deem to be "best" Smiley

Don't include the cards, cases, or PSUs.

Asrock 890GX-EXTREME3 is a good choice with 3 double-spaced graphics card PCIe slots (no adaptor cables needed).

Japanese caps, nice layout, BIOS-based core unlocker, and takes nice-and-cheap AMD Sempron 140s too.

Hmmm I would probably buy this one (motherboard) instead of the one I picked... damnit! actually wait no, i'll take the 5 pci slot board, since it's dedicated mining rig i'll run linux on it instead and therefore the 5 slots is favoured instead of 4 slots; but if your running windows go with the ASROCK board Calibre selected

I'm happy to run Linux with this - only reason I don't run Linux on my current computer while mining is that fglrx cannot be forced to use a resolution, unlike radeonhd, which is happy to ignore EDID and allows xrandr to work.

I guess I'll update it to 3+, not 3/4... sorry! Sad

edit: Just to note, I'll try to make the decision today, and I definitely will by Sunday afternoon BST....

The five slot board with Linux is fine if you're okay with risers, DIY mounts, and creative cooling solutions. It's a personal preference of couse, but I prefer self contained rigs that can be mounted with stock components and without too much fiddling - which helps maintain their re-sale value too. :-)

AM3 Sempron 140 is cheapest cpu I can find; so yeah Calibres CPU is winner imo (i've been looking at building this same rig)

The reason I mentioned no case is because I plan to use a traditional DIY lego, duplo and K'Nex "case". I already use it for an old server in my cupboard, so the technique is proven... Tongue

Asrock has no real warranty, you have to deal with store for warranty.
I won't be buying another asrock anytime soon.

Aww... just realised, a socket with holes! Reminds me of rebuilding old dell computers! Smiley

lightspeed, calibre...

I like both suggestions, although I'd go with calibre's

Calibre, would you be okay if I gave you 0.15 and lightspeed 0.1? Shocked

175USD is quite a lot more expensive than the asrock mobo, although if the asrock mobo is unreliable/no support from manufacturer, then I don't know. Still more expensive than the two I would consider, sorry Sad

If you don't want 4 gpu or don't mind buying risers, I agree

I'm absolutely fine with the split.  Smiley

Some good choices here in general which should prove useful for other miners.
