What SFP's are these compatible with? Do Cisco SFP-10G-SR or Finistar FTLX8571D3BCL work with these cards? What are peoples recommendations for SFP+ compatibility?

looking at the pictures more closely, these are half height cards aren't they?
Mellanox makes only half height cards :D
(But there are low and full profile brackets so that you can use them in 2u and 3u+ chassis)

Look like lowest he will go is $18 per CX3 10G nic on counter offer + $18 to ship 4 cards. Least that is what a buddy of mine just closed on so YMMV.

Any ideas where to find _really_ cheap 5m SFP passive copper cables that works on this?

Although I don't know about these cards in particular, I believe passive cables work for any card. I bought New Dell/Force10 10GBe SFP+ 5M Copper Cable Assy CBL-10GSFP-DAC-5M 5CN56 | eBay few weeks ago for Intel x520-DA2. Seller accepted my offer of two for $12 each with free shipping.
Hey! Thanks for the link. I ended up ordering them yesterday via fs.com - they cost around $20ish which isn't bad.

Another question; does anyone know where I could find full height brackets for these cards? Really keen to start playing with these.

price is now up to $23 + $15 s&h. I guess the seller is thinking they could get more or was burned by the previous price.

i don't know for sure if these will fit, but this Chinese seller has a lot of Mellanox brackets:

beijingtape85 | eBay

You could contact Mellanox too, but I think the last time I did that, in the USA it was $10 + $10 shipping so it came out to more than eBay, but I guess you get a genuine Mellanox part.

Prolly going to order from Mellanox as the parts cost the same as the Chinese seller wants postage fee's something they don't have to pay (government provides free postage abroad via ship routes - or is it a legend).
