Splitting arrays was never really a good thing to do.
It was, just before you were in IT.

Dell R630 - 10 2.5'' drive bay chassis - I normally buy 2U servers for the drive capacity, but I figured 10 drive bays should be pretty good as I can use RAID 5 now to get better capacity and still have half my drive bays empty in case of future expansion.
Go for the R720/xd. It's not that much more in the long run and you will be able to upgrade/add storage on demand. It's a really nice system.
2xIntel E5-2640v4 10-core 2.4GHz - This seems to me the best compromise between cores and GHz. I currently have 28 vCPUs provisioned.
You could probably get away with 8-core processors. You may want to look at the total average GHz used (very easy to do with ESXi) over a week or two. This will give you a better understanding of how much actual compute capacity you'll need. Not the best measure of CPU usage but it helps get an idea. Windows licensing (and ESXi) aren't cheap and since they are both done via CPU now you need to be aware of that.

Have you considered getting another R720 that matches and instead of Veeam replication, using Starwind for a real high availability setup for the same or less money?
-
@scottalanmiller I was just about to say that . . .
-
Which a nice thing about using Starwinds is you wouldn't have to worry about your database, or possible corruption while trying to back it up.
They even have a free version for life if I recall correctly.

Yes, it's all free. Only the GUI isn't free after the first month.

@scottalanmiller Briefly, my concerns with that though is the way I understand Starwind works with VMware is I need to create Windows Server VMs which host the storage I think? It just seemed like it added a little more complexity.

A couple thoughts there...
- As a non-profit, this affects you less than most.
- It's not the complexity that it feels like and results in a vastly superior result, so a bad factor to use in deciding against it.
- It adds complexity in that you need to make a VM, but reduces complexity by giving you a simpler storage system.
- This is complexity that only exists because of the desire to use VMware, move to Hyper-V and there is no need for the VM and that complexity vanishes.
-
@scottalanmiller So, a few questions:
- Would it matter that 1 host would be SSD and the other HDD?
- Would it matter that the old R720 has less storage than the new server?
- I posted this on SW a while ago because I was trying to understand where vSAN fits in: https://community.spiceworks.com/topic/1976492-replicated-local-storage-virtual-sans-versus-application-ha and from what I had read (and some comments you had made to other posters) it seemed like things like SQL, Exchange, AD, etc are usually exempted from other types of HA in favor of their native application HA so I didn't really know if SQL would be a good candidate for vSAN.

Yes, you want them to match.

Yes, which is why I mentioned the benefits of getting a cheaper server so that you save money while also getting big benefits from it.

That's totally true. The question is then... ARE you using application layer high availability for those things? Because you wouldn't use Veeam Replication either, if that were the case.

Oh, one thing I was really curious about too, would it make sense to get an extra drive as a hot spare? Normally with OBR10 and spinning HDD, I'd put every spindle into the array, but since SSDs are going to give me plenty of IOPS and capacity, I didn't know if it is a good/bad idea with OBR5.

The rule of "no hot spare ever" for RAID 5 still applies. If you were going to do this, you would do OBR 6. OBR6 can make loads of sense here, but OBR5 + HS does not.
But it is up to you, depends on cost and risk aversion.
