Feb 12, 2015 I've been doing some research into the process and for the most part, it doesn't seem too difficult with installing an SSD as a 2nd drive into the Mac Mini (thanks to the thousands of YouTube videos on how to do it).
When seating the bottom RAM chip you may have to apply a little extra side force to get it to seat properly. I put in the new RAM and just got a beeping sound upon starting. I then put the old RAM back in and got the same result. Here is the solution I found on the Apple discussion board. 'Take a small flat head screwdriver and after you put the memory in slot 0, put the screwdriver between the top of the mac mini and the memory then turn the screwdriver a little to exert pressure on the memory into the slot.
Do it on both sides of the memory.' This worked for me. The cowling has a notch close to the midpoint of the flange that goes under the outer case, which slides onto a standoff screw attached to the logic board. I used a Sharpie marker to put one 'alignment mark' on the inner edge of the outer case. I put another alignment mark from the midpoint of the cowling notch out onto the visible part of the cowling.

This made it much easer to reassemble, especially since my standoff post provided a tight fit, which, when I did this the first time, felt like 'it doesn't fit.. It also helped to insert the end of the cowling closest to the heat sink first, which acted as a 'fulcrum' for the cowling to 'click' onto the standoff post. When reassembling this aerial plate, it may take a very strong force to align the side lips with the screw bays. The circular edge on the body is meant to slot into the plate by less than 1mm. I followed the rule of thumb, which is, if it takes an unusual force, stop and think it out to avoid a disaster! Then, I hit on using a paper clip to get around this problem. Make a paper clip L-shaped to loop through a hole close to the edge of the plate, where the slotting is not deep enough.
Gently lifting the paper clip, slide and push the aerial plate in place. This worked like a charm without using a strong force.
I was installing an SSD in my mini and when I got to this step, an issue came up. The two 6.6mm screws on the antenna plate screw into one side of, and secure, the hard drive. The problem was the SSD was thinner than the original hard drive, so when I tried to reassemble, the hard drive sat too low for the screws to reach it. Windows 10 additional monitor. Here's how I got around the problem. I loosely attached the antenna plate to the hard drive, leaving plenty of wiggle room between the plate and the drive. I also left the two stand off screws on the logic board off to give me more wiggle room there.
With the SSD attached to the antenna plate, I carefully connected and stowed the Bluetooth cable. Using the antenna plate as a handle, I was able to guide the SSD into the hard drive mount.
Once in place, I tightened the 6.6mm screws more, which raised the SSD to the proper level. After insuring that the screws all lined up, I installed and tightened the logic board, then the other antenna plate screws. What finally helped me was to check things one at a time. To check the tongue-and-groove fit, I installed the antenna plate by itself, with the hard drive removed.
I used a spudger to pry open the groove on the antenna plate, since I had closed it a bit by forcing things. After the antenna plate was going in by itself, I focussed on the hard drive. At first, I was pre-attaching the hard drive to the antenna plate, but this makes it hard to see if the hard drive is going in as far as it should.
Getting the two protruding screws on the hard drive into their holes is tricky (I found turning the Mini upside down to use gravity helped), but for me it was some wires at the side of the hard drive space that were getting under the drive and making it sit up high that was the problem. Once I got the hard drive in, and then the antenna plate, I could get the last two screws which hold the drive to the plate to catch by turning the Mini upside down and tapping it on top to bring the hard drive close to the plate. I decided that there was a greater risk of breaking something by not removing the logic board than by removing it.
