Hope this helps someone..
The result is WELL worth it! Before my Mac Mini was constantly deadlocked because I always have dozens of Chrome tabs open, Safari, and the thought of opening X Code is out of the question. Now I can flip between all 3 of them like nothing!!! I swear it runs like greased lightning!! I am so happy, I can't even imagine a better result. I thought FOR SURE I would still need to upgrade from 4GB to 8GB RAM but NOPE! Its so fast I can't see any reason to drop the $50. The "page file" / "virtual memory" gets located on SSD and that's so fast it acts just like RAM. Awesome!!
I also used a special guide I found on the web that uses CoreStorage commands to make a Fusion drive out of the factory HD "Macintosh HD" PARTITION and not the entire DISK. (Something like disk2s2 instead of just disk2). That way, my factory HD actually keeps it's 650MB RECOVERY HD which allows you to still do rescue/recovery stuff just like factory. Otherwise you could lose that if you erase both HDs and just create a new Fusion drive. (Although when I read the 10.9 Mavericks Installer log details, it seemed like there was a check for a Recovery partition where maybe it would've made one?). Apple's Support website has a tool where you can download a Recovery Assistant .DMG that lets you create the Recovery Partition on your blank drive.

2. When I was reassembling my Mac Mini, the top HD seemed to just flop on there and I was concerned it wasn't going to really be secured by anything. Even worse, it seemed like my 2 HD-to-logic-board cables were going to be pinched when the top HD got installed! Then I realized if you tip your Mac Mini sideways (pretend its a book and stand it on it's "spine"), gravity will pull the hard drive locating pins into the 2 grommets, and you'll realize the top HD actually sits a fair bit higher than it appears, and there shouldn't be much risk of cable pinching when finished.
1. My power supply wire harness (black maybe 8-wire?) did not want to return to its original position, making me feel like I was jamming something too tight when I reinstalled the logic board. The iFixit guide said to ensure the power supply harness routes underneath the power supply but that left too much extra wire bunched up where it meets the logic board. I wish I had paid closer attention to how the factory routed the power supply wire harness so I could've put it back that exact way. My suspicion is it runs in a tight narrow gap between the top HD and the power supply.
I used this guide for my Mac Mini Late 2012 for SSD upgrade to be a Fusion Drive with my old 64GB Crucial m4 SSD. I can't believe how well it works!! SO much faster I am not even going to bother upgrading the 4GB factory RAM!
Just follow the iFixit guide very carefully and cautiously.. I spent about 2 hours doing this on the kitchen table. It helps if you have good lighting and good tools. You will have to literally gut every part out from the inside of your Mac Mini until it's nothing but an empty aluminum shell...
I used everyone's advice and moved my factory 500GB Hitachi HD to the new location, and put my SSD in the old location.
When I was putting it back together I encountered 2 obstacles: [see next comment]
