The clear is a great case, no question, but it is not for everybody due to being a reverse configuration AND having a top mounted PSU. There is a reason why PC case form factors and manufacturers moved away from top mounted power supplies in the past. It screws up the normal convection current where cool air moves down forcing heated air up.
It is a misnomer that heat rises. Heat does not "rise" on it's own. It is moved upwards by cooler, denser air moving down due to the stack effect.

Probably overkill for your purposes but a good read anyhow. It very much is relevant to PC cooling and I'm not sure why they went back to this configuration, but I personally don't care for it as it is backwards from what we've come to understand as being more efficient in PC cooling.
Still, I guess with plenty of fans and significant negative pressure arrangements, it might be a moot point. I still don't like it. I will not be buying any reverse configuration cases for myself. If somebody wants me to build them a system in one, I'll point them to this same logic and then if they want me to still do it, fine. I have no problem with that. Its YOUR system, and you pay me to build it, not the other way around. No qualms at all with doing that.
So, between the 750D and the Enthoo Pro. They are very nearly the same case in looks and function. Basically.
The pre-modified one I linked to looks MILES better than the stock Enthoo Pro case, but you may not care about that at all and simply be ok with the normal side panel of the Enthoo Pro. That's all fine and good. I don't care what your case looks like any more than you care what mine looks like, if we get down to brass tacks about it, right? It's a good case no matter which way you go, and since function is more important to you, it's also about fifty bucks cheaper than the 750D.
However, the Enthoo Pro case is plastic. And it can be fragile if you are not the type to be at least moderately careful around it, or have pets or kids that might damage it. Or it's in an environment where your drunk buddies might bash into it. Or whatever.
I've broken the tabs off one of them by accident, which was TOTALLY my own fault. And by tabs I mean the plastic 3/4" long nipples that fasten the front and top panels on, that stick down into retention holes. It can happen if you don't pay attention to what you are doing but so can it happen in a similar fashion with a great many cases. Problem is, it happened taking it out of the box. Again, it was my own fault. The five other times or so that I've built in that case it has not been an issue as I was aware of the potential for those "nubs" breaking off.
The case is fairly light for a full tower case, and that is both an advantage and a disadvantage. An advantage because it make moving it around or working on it a bit easier. A disadvantage because obviously, being light due to being mostly plastic except the frame, it is also weaker and more susceptible to incidental damage from bumps and drops or not being careful with the panels as I said.
The 750D on the other hand is steel frame with brushed aluminum panels. They are less likely to be damaged or cracked. But they are also heavier. I guess that is the main disadvantage of that case is that is likely to be heavier than any comparably sized plastic paneled case. It should be a lot more durable though. I have only ever built one system in that 750D airflow edition case and I found it to be of extremely good quality.
For cooling, both support dual 120 or 140mm fans up front, and the 750D comes with two 140mm fans while the Enthoo Pro also can support a 200mm fan up front, and comes with one. Dual 140mm fans offer more airflow than a single 200mm fan but a single 200mm fan makes less noise than two 140mm fans. Pick your pleasure on that one.
They both offer three 120mm or 140mm fan locations up top, plus the Enthoo Pro can do a 200mm fan in that location. Again, up to you on what you want or even if you want at all, although I'd advise at least getting one additional fan for that location in the top back, likely a 140mm.
They both come with a rear 140mm fan, so no boon or bane there. Fan quality is probably a push. Included stock fans are rarely great examples of what a fan should be, even compared only to other fans sold by the same company. Nobody is giving away great fans with their cases so you get fans that move air but are neither fantastically quiet or fantastically great air movers with terrific static pressure. You get ok fans that are probably better replaced with quieter, high performance models at some point or another.
I call it a draw overall but there might be something here that leans you one way or the other. I will note too that the Phankteks case comes with a PSU shroud which somewhat helps to protect the PSU from, well, I dunno what aside from a spill but mostly it is an aesthetic feature and just makes it look a lot cleaner overall. This is not always a prerequisite, obviously. If it's your gaming rig or whatever, then yeah, if it's a workhorse only, who cares.
If it were me, buying for me, I'd probably opt for the Enthoo Pro WITH the large side panel from MNPCtech. I like the work that Bill Owen does and he seems to be a professional. If you have not seen examples of his work, Google MNPCtech and take a look at some of his stuff. Or click that link above and browse his site. Or if I needed/wanted to get almost the same case, didn't have an issue with plastic construction and wanted to save fifty bucks to put elsewhere in the build, I'd go with the regular version of that case and forego the custom side panel.
If however I simply wanted a beast of a case, without going completely captain crazypants on the cost, that was durable and had most every feature that most people could reasonably expect, I might go the other way.
Sorry if I can't be more help than that, but I can't decide FOR you, I can only offer you facts that allow YOU to make the best decision for YOU.
