The AIO platform design is much more akin to laptops than the desktop PC due to its small size, restrictive form factor, and minimal aftermarket upgrade options. GIGABYTE's new Thin Mini-ITX H77TN and B75TN looks to expand the All-In-One PC design with custom build options.
The Mini_ITX H77TN and B75TN are both with Intel's AIO specs. The also support LGA 1155 Intel processors, two 204-pin DDR3 laptop DIMMs, 4x PCIe slot, and mSATA support all with a 17 cm x 17 cm x 2.3 cm design. The ultra low profile allows DIY builders to include this board into very tight spaces with the help of creative cooling solutions.
While All-In-One (AIO) PCs and Mini-ITX are not new, you can now start a DIY project within the AIO spec. I am sure we will see the GIGABYTE H77TN and B75TN used in a number of interesting mods as well once they are available.
