Hello Guys!

Working with the Corsair 250D:
For a first time ever build, it was an amazing experience! The only problem I faced is the small space I had to manage the cables and installing the H100i. I had to go back to the manual to make sure how to install the H100i after installing it wrong couple of times.

Time for my first build: 7 Hours + 1 Hours of OS and drivers installation = 8 Hours

Parts NOT to order with the Corsair 250D:
PSU: Don't even think of getting the RM850 for this case, the flat cable design and the 90 degrees angle connectors for the SSDs/HDDs are pain in the a**!!! very hard to bend, no cable management can be done and very hard to install the cables on the SSDs/HDDs because of the 90 degrees angle connectors. My cables are in a huge mess now and kind of blocking the intake fan air, air is still going through though.

Front Intake Fan: Don't try installing a 200mm fan with the H100i because it won't fit. the Cooler master MegaFlow 200mm had extra edges that hit the Optical drive clip points and cant be installed (even if the optical drive is not installed).

My Airflow Setup:
- 1x 140mm front intake fan @ 1100 RPM
- 2x 120mm side intake fans on the H100i @ 1300 RPM (used Silverstone 3.94" PWM Fan Splitter Cable to connect fans to the CPU Fan header)
- FanXpert 2 is used
- Dust filters removed from both sides (left and right)
- No exhausts, the small case should help exhausting the air passively and positively through the back

Overclocking:
Processor: from 3.5Ghz to 4.3Ghz at 1.275 volts (I think I have a bad chip, can't do 4.4Ghz at 1.300 volts)

GPU: Power Target 106%, Temp Target 90C, GPU Clock Offset 75Mhz & Mem Clock Offset 300Mhz on EVGA Precision X (Let me know if you have any recommendations)

Temperatures:
Ambient Temperature: 21C - 23C

CPU at Idle: 22C - 30C*
GPU at Idle: 21C - 26C*
Motherboard at Idle: 21C - 26C*

* Depending on how many hours the PC is idling

CPU at Max load (RealBench): 69C
GPU at Max load (RealBench): 42C - 50C

CPU at Normal usage/Gaming: 30C - 40C
GPU at Normal usage/Gaming: 30C - 40C
Motherboard at Normal usage/Gaming: 24C - 28C

RMA:
I think my H100i has issues, sometimes the LED blinks red and there is a buzzing sound coming out of the pump but the temperatures are normal between 25C - 34C. Im still using it because most of the times this issue don't appear.

Final Thoughts:
- This is the best gaming case i've seen in a while, low temperatures and excellent airflow especially for the GPU, the side fans help air go in and hit the back of the GPU to cooler it and the side grill helps exhausting the GPU air our easily.

- The SSD/HDD trays located in an excellent place.

- You can have a good cable management if you use the right cables, DO NOT use flat cables!

- I own a Playstation 4 and when the news came out about the Steamboxes I was immediately interested, changing your hardware and playing games at max graphics while having the shape of a console really got my hyped. The only problem about the small form box size is temperatures, so that's why I decided to go with the mini-itx form.

- Dual graphics cards (ex: GTX 790/ 290x x2) should come soon and it will be a perfect addition to a mini-itx PC (if it fits)

- I read about a lot of mini-itx cases for 2 weeks before ordering the Corsair 250D, it's one of the best on the market for airflow/temperatures and you can fit top end hardware easily like I did

Please let me know if you need to know anything else! :)

I'd appreciate your comments regarding overclocking the CPU and GPU

Thank You!!
