With the price of ConnectX3 cards capable of 40Gbe and switches hitting $1500 or less for good # of ports of 40Gbe (some all)...
Is there any reason to even consider buying more 10Gbe cards? I mean they're $60 for single port now, no more $25-30$, and dual port that were $60-80 are now $130+ again...
Why not just go 40Gbe all over for a home lab, small business, etc... it seems as long as you're not going past 12-16 ports (cheaper switches) you could go ALL 40Gbe?? Heck, a 40Gbe only switch + LB6M would cover a lot of ground, and be cheap cheap. Those of us who got the DACs for 40Gb and 56Gb should be sitting even more affordable!!
Just thinking out loud, looking for error in my thinking... ?

Well with the EX4300 reported at roughly 45Db that is very reasonable acoustic-wise for a 40G capable switch.
The other big downside for most 40gbe switches is the power draw. You can get 10gbe switches that idle around 15w or so. Plan on closer to 100+w for most 40gbe switches at this point. Even with these junipers I am seeing 70-80w power draw at idle. Luckily for me it will replace two of my switches in use so that makes the power draw a bit more acceptable
@Patrick exactly... so why not go 32 port 40Gbe? I know that's what I'm trying to find a deal on 
something in the 24-32 port range.
$25-30 is what I paid for single port Intel 10Gig SFP+ based NICs
$30-50 or so for Mellanox connectx2 10G
Now the Intel are $50+ 2 port $100+
Or $60-70 for 2port 40G -- seems like a no thought , that's the way to go... trying to see if I'm missing something.
It's not like 24x 10G ports are a silent switch ie: LB6M
Now what would be badass would be 30x 40GBE and 2-8x 10G so you could connect some LB6M/s.
Or, I guess just find another 10G switch that has 40Gbe and stack with 1 or possibly 2 ports... still would ROCK!!!!
I wish those ConnectX5 100Gbe were not $1k+ ha ha!!
Less of a concern for me, personally, on the capacity/size I'm working with... but ya know, why not? HAHA GOALS!!

Thanks for the information! I'm a little hesitant to jump in on the CLI interface for switches. Been using Netgear switches with their WEB GUI which has made things very simple.
My EX4300 just arrived from UPS. Looks good and the seller did a fantastic packing job (gotta luv overzealous packing jobs!!!)
Awaiting my JPSU-350-AC-AFO PSU from China now, 4-6 day DHL ship times they say. We shall see. Wish those 4 port 10G EX-UM-4X4SFP modules weren't OUTRAGEOUS lol. Gonna have to wait those out just like I did the switch and be patient on hunting a deal!

Because they are currently shipped to hyperscalers and not to "normal" enterprises.

Fair enough I guess, Using 40/100 for uplinks already, just never saw much 25 stuff, I thought it may have been likes the 2.5/5 stuff that never took off despite it being a good idea, dead now as 10 should be standard on anything except it's not and still so many 1G ports but then again the power cost of 10g copper is rather unattractive unless you need the bandwidth.
How hard are these switches to setup for basic use? I don't need to setup anything fancy like VLANs.
Do they require licensing or subscriptions, or can I just guy one off of eBay and plug it in?
Sorry if these are obvious questions, I'm not much of a networking guy.

Most of the switches can be used immediately, only the fancier stuff (vlans, dcb,pfc and so on) need additional configurations.
Licenses/supscriptions depend on the switch manufacturer. Juniper switches for example requiere licenses for layer 3+ protocols, other need supscriptions for firmware updates. You should look that kind of information up before buying a switch.
