The nice thing about the TT core cases, I have the X9 is the versatility, especially if you are willing to experiment.
I wanted 3 XSPC RX 480 rads housed in it and I found a way. I ditched the HDD cage. Too big and bulky. I'm running 2 Samsung 850EVO 500Gs in Raid 0 plus a 2Tb WD Black for data storage.
I had an Old Chieftec 2.5" bracket that perfectly fit both ssds. After a black paint job and mounting with a few bolts to the bottom, both ssds were mounted in the middle.
On the left side bottom as you look at the X9 from the front, rear to front, I have mounted, my PSU (PC Power & Cooling 1200W), my 2Tb WD (used a cheap black bracket and my XSPC dual 5.25 slot twin D5 pump/reservoir. On the right side lower I have one of my three RX480 rads using the mounting brackets previously used by the HDD cages with the remaining 2 480 rads mounted in the roof.
This setup allowed enough room for a DVD drive to be mounted in the front top. I have a NZXT 6 channel fan controller (2 fans per channel) controlling my 12 Gentle Typhoon fans}.
It isn't "fancy" or "blingy" but it sure works well. BTW, Apollo Caster Company makes casters that perfectly mount up to the bottom holes on the Core X9. Life is a lot easier when working on it.
Here are some older pictures when I hade a GTX 980 TI in it (now GTX 1080).
Hope this helps.
