It took me 22 months from I bought the motherboard until I finished everything. Money and time was the main obstacles. Making all cables from scratch (not SATA, I wish I could), custom made radiator grill inside (don't think anyone has used a Mo-Ra 9x120 pro fitted in a cabinet before), testing and swapping for new hardware when I wasn't satisfied, and what not. The last 3 months it's just stood there waiting for me to make the 5 last internal USB cables 🙂

The finished product, Poseidon-03, is only waiting for the new GTX1080 (running a GTX 690 atm), but the card is a week away.

Only OC'ed to 4GHz, so far and CPU is well below danger level (90C I think).
