What does SFX PSU (Optional) mean? Can I use a regular PSU?

I would stick with SFX. My original plan was 2 2.5hd at the bottom and one 3.5 on the side. You will notice some high temps (in such a small confined space) and I started hearing my stock fan on my Intel chip. I went ahead about got rid of one 2.5 hd. Moved the other 2.5 under the optical drive bay, added a Noctua 120mm at the bottom to suck in air, and replaced the stock cpu cooler with a Noctua NH-L9i 95mm.

i have 2 questions, , is only compatible with psu sfx ? include Slot-In Slim ODD ? thanks

Yes only sfx. Does it include the slim odd, No. Is the only option for of Slim ODD a slot loading drive, yes.
