Intel B75 Express, which provides native support for USB 3.0 and SATA III.
The is a Micro-ATX motherboard commonly used in desktop systems like the Acer Predator G3620 and Gateway DX4870. Official service manuals for these motherboards are generally not available to the public, but the Acer Predator G3620 Service Guide contains the technical specifications and internal jumper/connector information required for maintenance. Core Specifications Form Factor: Micro-ATX. Chipset: Intel B75 Express. Acer Ipimb-ar Rev 1.02a Manual
Since the board has no onboard video chipset, you must have a CPU with integrated graphics (like a Core i3-540 or i5-650) or a dedicated GPU plugged into the PCIe x16 slot. If you use a CPU like a Core i7-870 (Lynnfield), which lacks integrated graphics, and you have no video card, the system will power on but give you a black screen.
Connect the momentary reset case button cable. Polarity is omnidirectional. Pin 9: No connection (NC). 2x SATA III (6Gb/s) and 4x SATA II (3Gb/s) connectors
The integrated rear I/O shield exposes basic workspace and peripheral connectivity:
The hardest part of reusing an OEM motherboard like the IPIMB-AR in a custom PC case is configuring the front panel headers. Front Panel Header (F_PANEL) I/O Headers: Front Panel header
Never install a CPU that exceeds a . Doing so risks destabilizing the un-heatsinked Power Delivery System (VRMs). Verified Compatible Processors
Requires a 4-pin or 8-pin ATX 12V connector located near the top-left CPU socket area. Common Troubleshooting Steps
The IPIMB-AR is a Micro-ATX board built on the Intel B75 Express chipset.
The Ipimb-ar was a legend in the DIY community, but for all the wrong reasons. It was a proprietary beast, a customized variant of an Intel board that Acer had locked away behind a wall of silence. No official manual existed in the public eye; it was a "ghost board."
