If you're having a problem finding the parts that iNTiMiDaTe xX has listed under his solution, here are some other locations that you can check out. I found the parts in these specific locations as I was going for the achievement on single player with the easy difficulty.

The part in the infirmary is the only part that doesn't change locations.

The case you can find near the cafeteria. If you face the cafeteria, make a right, reach the end of the hallway and make another right and the case is laying on the floor directly across from the afterlife box.

The compressor is in the Warden's Office but if you face the location of the mystery box that's inside the office, you will see it sitting in the corner to the left of the mystery box.

You have to obtain all 3 parts before you build the upgrade which means that you can't use the building tables until you have all 3 parts with you.

The only spot that seems to be guaranteed, is the part in the infirmary but after I got the achievement, I started another game to see whether the parts were going to be in the same locations I have listed and they were but now for some strange reason, when I tried it on normal, the compressor was in the location that iNTiMiDaTe xX has shown in his video but the case was in the location that I have listed. So I put it back on easy and the parts were located in the same exact spots that I found on the normal difficulty. So the parts' locations WILL vary no matter what but the locations that I have listed, will give you an idea on where to look if you don't come across them when looking at the other solutions.

Edited: The part in the infirmary does change locations as well. It can also be in the bathroom section of the infirmary to the left of the single bathtub in the same room as the mystery box instead of on the table in the same room where the hole is during the afterlife phase.

2nd Edit: There are 3 alternative locations total for these pieces in which i spotted the case in the area where you first start the game behind the first cell door you open in the small library room with the 2 windows. The compressor I spotted in the Warden's Office in the Speed Cola Perk Room on the floor in the corner and the green bottle was either in the room with the single bathtub, or the room next to it (I don't exactly remember) but it was on the floor in a corner.
