This is necessary to connect the video card
Minisforum decided to take the idea of a mini PC that can be turned into a full-fledged gaming PC forward with the introduction of the B550 Pro. This is a slightly modified version of the B550 , which debuted in February.
The main difference is in the body. B550 is a classic mini-PC, which can be connected to a special frame for an external power supply and video card. In the case of the B550 Pro, it is based on the same mini PC, but the frame has turned into a full-fledged case that is assembled on top of a mini PC. In this form, the product looks more complete and there is no problem with exposed components.
Take a mini PC and install it inside a special case to get a larger mini PC.
While there are not all the details, but support for Ryzen processors up to Ryzen 7 5800X3D is already mentioned, which may hint that the new product will be available, including as a Barebone kit. In any case, the original B550 only relies on the Ryzen 5 5600G and Ryzen 5 5600X.
The dimensions of the PC in the case of modernization are 170 x 160 x 320 mm. You can install a 3D-card up to 300 mm long into the case, that is, not any modern model will fit.
