• Low power consumption
• Passive cooling (no CPU fan)
• Scalability

Sam440ep was the first modular motherboard produced by ACube Systems Srl.

• 400/533/600/667 MHz AMCC PowerPC 440EP SoC processor
• Cache L1/L2: 32KB/-
• 128/256/512 MB 266 MHz DDR SDRAM soldered to the motherboard
• 1× 32-bit, 33 MHz PCI slot
• 1× Flash memory device controller
• 4× USB2 ports, 1× USB1
• 2× Ethernet 10/100 ports
• 4× Serial ATA ports
• Cirrus Logic CS4281 and Realtek ALC655 audio
• ATI Radeon Mobility M9 graphics with 64 MB VRAM, s-video and DVI out.
• GPIO expansion connector
• Lattice XP expansion FPGA

The specifications are the same as for the revisions before, except for:

• 1× DDR RAM slot supporting up to 512 MB RAM (in place of soldered RAM modules)

There is no graphics chip on the Sam440ep-flex, so you have to use a PCI-graphics board.{{cite web

OSNews review provided view by someone who never used AmigaOS computer before: Thom Holwerda commended silent CPU-fan-less operation, but criticized higher price. His evaluation of AmigaOS was mixed; although the platform offered "whole new world of technology to explore and play around with", it was still a relic of the past mainly due to lack of modern features like memory protection and unusual user interface. Review of the Sam440ep in the Amiga Future magazine noted performance comparable to older AmigaOne generation, but criticized non expandable RAM and lack of legacy interfaces (ATA, floppy). Also some features of the new board were still unsupported by AmigaOS (USB 2.0).{{cite magazine |last=Wahnem|first=Sascha van|date=January 2009 |title=SAM440EP mit AmigaOS 4.1|magazine=Amiga Future |language=German|publisher=APC&TCP|issue=76|pages=37–38}} Testing the 800 MHz variant of the Sam440ep-flex, Amiga Future highlighted CPU speed behind the MicroA1 (750FX 800 MHz), but surpassing it in graphics, memory and harddisk performance.{{cite magazine |last=Preinsack|first=Anton|date=July 2009 |title=Samantha on speed SAM440EP-flex mit 800 MHz|magazine=Amiga Future |language=German|publisher=APC&TCP|issue=79|pages=37}}
