Im gonna replace the motherboard of the i mention at the title because im planning to buy new partsfor own pc so ill put my old components to the lenovo pc. i suspected that lenovo pc is using an itx motherboard but maybe im wrong and the motherboard im going to replace it is a matx board and i heard that some pc companies use proprietary parts and mounts for their PCs.

looks to be a mATX board.
the problem you will have with replacement is the power connector, the power supply in the lenovo does not have the standard ATX power 24-pin and cannot power a standard board.
you are looking at a chassis, PSU and motherboard swap to change the motherboard.


you can see the PSU connector has 10 pins and 2x4-pin blocks

its a non standard PSU. unless you can find one in that form factor with the proper power connectoars a standard unit will not fit which calls for a new chassis to house the PSU.

the differences in dimensions are easy to see.
