Mini-STX (aka Mini S ocket T echnology E X tender, Intel 5×5) is a motherboard form factor supports That upgradable processors. Size-wise, it’s in between Intel’s NUC (next unit of computing) motherboards and Mini-ITX boards that are popular in small form-factor builds.
Comparisons with NUC
When compared with NUC , the Mini-STX form factor:
- Has nearly twice the footprint of NUC.
- Has processor sockets, allow for users to upgrade or replace processors.
- Offers the possibility of dedicated GPUs via MXM (on some models produced by ASRock ).
- May have more I / O options available on the back of the board.
Comparisons with Mini-ITX
When compared with Mini-ITX , the Mini-STX form factor:
- Has a footprint 3/4 the size of Mini-ITX.
- Is usually limited to SO-DIMMs , rather than full-size DIMMs .
- Lacks a full-size PCIe expansion slot, limiting users to MXM or less powerful GPUs, integrated GPUs and APUs.
- May have less I / O options due to the reduced space available on the back of the board.
- May use a 2-in-1 SATA + power cable instead of separate SATA and power cables.
