No. Simple as that.
That's $1,500 USD, so pushing $2k Canadian. While CF 290X's are decent, you're also giving up warranty etc.
Those are older components - and an Enermax PSU. While Enermax have a couple of good PSU options, I wouldn't bank on the seller actually used one.
It's probably an 'ok' PSU at best.
64GB RAM is also pointless for all but the most extreme tasks.
For the same cost (or less) in CAD, you can do much better. I'll post a build to give you an idea.

You could scale it back significantly & still have an amazing rig (i5-6600K + GTX 1060 for example).
No shipping, all quality components and you'll actually get warranty too
I look at it again, and there's no OS in the build either! So that's $2k CAD + ~$100 or so, at least.
A stronger single GPU is always preferred over either CF or SLI.
All in all, at $2,100 - $2,200 'all in' (CAD) you could pair an i7-6700K with a GTX 1080, or close enough.
Whether that's necessary though, depends on your resolution. 1060 is sufficient for 1080p, 1070 for 1440p, 1080 for 4K (in very simplistic senses anyway).
*EDIT* Nevermind the PSU comment, as I see it's a Platimax 1350W. A solid PSU (overkill, absolutely, but solid).
All of those components have the potential to be 3+ years old, so most are out of warranty (if warranties for the components are even transferrable to begin with). Judging from the post, overkill PSU etc, I'd expect everything has been 'ridden hard' too.
I'd say that Craiglist listing is worth.... maybe $800 USD / $1,000 CAD today to the right buyer - but that would be a select few buyers. Building new, with warrantied components would be a much, much better idea
