Yes. 4 slots, up to 3 GB seen working.

It takes DDR2-533 full-size sticks (DIMM).

SSD

Check the drive you have.

The reports don't show this model's drive type yet. Look at the drive in it: a 2.5-inch box, about 7 by 10 cm, is SATA. A small stick is M.2, and its label says NVMe or SATA and its length (2230, 2242 or 2280).

Power supply

Check the label on the power supply.

We don't have this model's power supply rating. It is printed on the supply's sticker, inside the case next to its fan. Prebuilt desktops often use a supply shaped for their case, so match the shape and the plugs as well as the watts. Small cases take a slim supply.

Rating: On the supply's label

Processor

It takes processors for the Socket 478 socket.

Processors in the reports: Pentium 4 3.20GHz (1). Prebuilt desktops often only take processors from the generation they shipped with, so stay with the ones listed.

Graphics card

Look for a full-length slot.

The reports don't list this model's slots. A graphics card needs a full-length (x16) slot, the longest one, and room in the case. 100% of these machines report a small case, which takes low-profile cards only.

x16 slots: Not listed by the firmware
Case: 100% report a small case
