I built this system last fall for my birthday and some of the parts I had from previous builds but I would say 90% of the parts were new. Some parts like the RAM and even the NVME drives reflect the crazy booms we have experienced in tech over the past two years or so. Crazy that two years ago I paid $200+ for a 2X8GB set of RAM out of desperation! My previous case was a Ncase M1 so my goal was to build the smallest most powerful PC possible. Essentially this is a complete overkill of a computer and looking back I am glad I got to build a HEDT Threadripper system, but the 16 cores for me was complete overkill since I mainly just game/stream on this.
The system was mainly built around the Sliger Cerberus and to my knowledge this is the smallest mATX case available at 18.5L. Up until this point I had never built anything but ITX systems so I thought it was great I could use a X399M board in such a small case, but now I understand that mATX in general is such a bastardized platform and very niche. Looking back I probably should have gotten the Cerberus X (ATX) so down the line upgrading my motherboard and chip would be easier.
I first started with a EVGA G3 1000 ATX PSU (got for insane deal) and I originally tried to use a EVGA CLC 240 with the EVGA G3 but there wasn't enough clearance with the way the tubes comes off the block. If you want to use an ATX PSU and AIO you will need an AIO where the tubes are mounted to the side and preferably are rotatable. So I switched to a NZXT Kraken X52 AIO with the TR4 adapter and I found that the G3 was really loud and kept the fans constantly on even on eco mode so eventually I sold it for a profit and bought a SF750 which is almost dead silent and has braided cables which are awesome for a case that doesn't hide cables well. Using any Asetek AIO with TR is possible it's just the plate doesn't cover 100% of the the chip. Temps were fine in PBO mode since it throttles at 68 degrees out of safety. I also temporarily has a push pull configuration on the AIO with some slim Noctua's but found too much heat was being built up since the front panel has no front cutouts. I briefly bought an Enermax Liqtech II from Amazon and after only two weeks it started to spike in temps and probably started to corrode, so that was returned and I constantly was paranoid about leakage. In the end I just wanted peace of mind so I switched to air cooling and the biggest full coverage TR4 cooler you can get for the Cerberus's is the U9 TR4. I also started with a RTX 2080 Ti XC which was more than enough for the system but around Christmas I found EVGA official on EBAY had a XC Ultra for $1150. I managed to sell my XC for $1075 and basically upgraded to a cooler quieter card for only $75.
I also first started out with all black panels but after seeing that some had slight over spray I emailed Sliger with photos they apologized and sent me two white ventilated panels and a white front panel for free. Sliger is also really responsive to any emails or phone inquiries and helped a lot with answering questions about compatibility.
7-15-19 I got a Intel 660P 2TB from Antonline for an insane $96 shipped. Not wanting to switch out any of my other M.2 NVME drives I bought a M.2 to PCIe adapter off Amazon for $13. So $109 for 2TB of extra storage not bad. I wanted to move the GPu down tot he middle PCIe slot and have the M.2 Adapter on the top but the card is too thick and come into conflict with the bottom fans, fan header, and RGB header so the PCIe adapter is bellow the GPU partially blocking it which does cause the GPU to run 1-4 degrees hotter sometimes depending on the game but still maxing out at 74 degrees which is still really solid. This also be due to the fact that it's the summer and without AC on from the start the card naturally runs hotter
