A small form factor (SFF) desktop or all-in-one PC fits this description best.
These compact systems blend desktop power with space-saving designs, using SO-DIMMs for memory, an internal power supply , and desktop processor sockets like LGA or AM4/AM5.

Why These Features Match

Standard desktops use full-size DIMMs, external-like PSUs in towers, and desktop CPUs—but they're not compact. Laptops rely on SO-DIMMs and batteries, not internal PSUs or desktop sockets. SFF desktops (e.g., HP Pro Mini or mini-ITX builds) squeeze everything into a tiny chassis: SO-DIMMs save vertical space, a small internal PSU powers it efficiently, and desktop sockets enable high-performance Intel/AMD chips without mobile compromises.

  • SO-DIMMs: Common in laptops/SFF for their smaller 2.66-inch height vs. 1.18-inch full DIMMs.
  • Internal PSU: Unlike laptop batteries, these have AC-DC units inside, like slim 150-300W modules.
  • Desktop socket: Supports beefy TDP (65-125W) CPUs, rare in mobiles.

Real-World Examples

Picture building a mini gaming rig or office PC: An Intel NUC or HP Elite Mini uses SO-DIMMs (up to 64GB DDR5), a built-in 90W PSU, and LGA1700 for Core i7s. All-in-ones like iMac clones or Dell Inspirons swap towers for screens but keep these internals. Forums buzz about this for home servers—trending in 2026 builds amid mini-PC hype.

"SFF desktops use SO-DIMMs for tight fits, internal PSUs for reliability, and desktop sockets for power."

Common Confusions

Some sources say "laptop," but that's off—laptops skip internal PSUs (battery- focused) and desktop sockets (BGA soldered). Quiz sites vary (all-in-one vs. SFF), but consensus leans compact desktops. No full tower fits SO-DIMMs typically.

Feature| Full Desktop| Laptop| SFF/All-in-One
---|---|---|---
RAM| DIMM| SO-DIMM| SO-DIMM 10
Power| Internal (large)| Battery| Internal (small) 1
CPU Socket| Desktop| Mobile| Desktop 3
Size| Tower| Portable| Compact

TL;DR: Small form factor desktops or all-in-ones. Perfect for desks without bulk—info from forums and specs as of Feb 2026.
