I'd go with something off of the Nexenta HCL for best results:

Though be careful, not everyone on the HSL is considered good.
I got bit by this when I purchased commercial edition. I was told my gear was wrong, though it was on the HSL (like my HBA) and support was quite resistant to helping.
In the end I swapped out the HBA anyway though it didn’t help, and eventually I wrote off my investment.
If you go the OI/Il route you should be fine, you don’t need the web interface and the python hackery that makes it work.
SuperMicro hardware is nice and stable today. 3U with 16 2 TiB drives + 2 SSD sled for the back, 96 GiB RAM, couple processors can be done for ~$9K. If you want dedupe then remember that you need ~8 GiB RAM per 1 TiB of storage. Not usable storage mind you, but total. So for a 32 TiB system you will need ~256 GiB RAM.
For ZIL you only need small SSDs, something in the 16 GiB range will be fine (and overkill). Mirror them together.
You can L2ARC as well, toss in a few largish SSDs as your read cache.
Compression can be done regardless of RAM settings. Today’s processors are nice and quick.
