Is the PDSMi still worth buying?

Only for keeping an existing LGA775 system alive or for a cheap spare-parts lab build. For new servers, a modern board with DDR4 or DDR5 and current I/O is a better use of money.

Does it support ECC memory?

Yes, ECC is supported, which is the main reason to pick a server board over a consumer one. Check that your DDR2 modules are on Supermicro's qualified list.

How much RAM can it take?

Four slots with a maximum of 8 GB total. Plan workloads around that ceiling, since virtualization and modern databases will feel constrained.

It uses Socket LGA775, so it takes Intel Core 2, Pentium and Celeron chips of that era. Confirm the specific CPU against Supermicro's support list before buying.

What ports and slots does it have?

Onboard Ethernet, VGA and USB, plus PCI and PCI Express expansion slots. There is no modern remote management controller.

What form factor is it?

Micro ATX, so it fits many small server and desktop cases. Check clearance for the CPU cooler and expansion cards in tight chassis.

Our take on the Supermicro PDSMi Server Motherboard

The Supermicro PDSMi is a micro ATX server board for Intel's LGA775 processors, built around an Intel chipset with four memory slots and ECC support. It pairs DDR2 memory with PCI and PCI Express expansion, plus onboard Ethernet, VGA and USB, so it can run as a small file, firewall or lab server without add-in cards. It is a legacy platform: LGA775 chips and DDR2 are long out of production, and the 8 GB ceiling is low by modern standards. Buyers choose it for cheap spare-parts builds and Supermicro's server-grade layout, not for current workloads; newer boards offer far more memory, faster I/O and lower power draw.

Pros

ECC memory support for data integrity
Four DIMM slots in a compact micro ATX board
Onboard Ethernet, VGA and USB reduce add-in cards
Supermicro server layout and build quality
PCI and PCI Express slots cover older and newer cards

Cons

LGA775 and DDR2 are obsolete, so parts are scarce
8 GB maximum is tight for modern server software
No SATA 3, USB 3 or modern management features
Older chipset means higher power draw per unit of performance
