You can find the same baseboard in the Socket 7 Review, there in combination with the CPU card P55T2D (430HX). Here we have the Pentium Pro pendant. This board is designed for excellent flexibility, 8 SIMM sockets and 5 PCI slots confirm this. Its very idiosyncratic design can cause mechanical difficulties: Not any case has enough free space for the CPU card! You will have to disclaim your harddisk and floppy bay or to look for a lavish case. Not only the card's extents represent an obstacle but also the fact that the air circulation must be provided to ensure a long life for your CPU(s). If you want to change the Pentium Pro card to the Pentium card, don't forget to upgrade to the correct BIOS version; otherwise your system won't even boot up correctly.
