Review on Fractal Design Node 304 - Black - Mini Cube Compact Computer Case - Small Form Factor - Mini ITX – mITX - Enhanced Airflow - Modular Interior - Includes 3x Fractal Design Silent R2 120mm Fans - USB 3.0 by Hemant Hemant ᠌

The maximum length that the video card can be is 310 millimeters, as stated in the specification. It was a perfect match for my Sapphire Radeon R9 290 Tri-X, which has a length of 305-310 millimeters and measures 305-310 millimeters. I believe that it is possible for you to install a longer video card if you give it a shot. According to what is said, the largest size that modular power supplies can be is 140mm. This is not quite accurate; you will need to unscrew four screws, remove the "frame" underneath the PSU, and then you will be able to install a modular PSU that is 160 millimeters in length (I have Seasonic X-650 installed). If you choose to install a discrete video card, you will only be able to keep one of the three hard drive slots available to you (in place of one there will be a video card, in place of the second there will be excess power cables, because there is nowhere else for them to be). The flow is excellent, but it is not even close to being optimal. Under load, a Sapphire Radeon R9 290 Tri-X can reach temperatures of up to 85 degrees when housed in a closed case (the valves on the case are all activated at the third speed), but can reach temperatures of up to 75 degrees when housed in an open case. As a direct consequence of this, I do not put the lid back on.
