MeLE Overclock 4C

Lane count sets the ceiling, and the gap is wide:

• PCIe 3.0 x1: about 985MB/s, the common budget wiring.
• PCIe 3.0 x2: about 1,970MB/s.
• PCIe 3.0 x4: about 3,940MB/s, the Overclock 4C's slot.
• SATA: about 600MB/s for comparison.

The slot takes M.2 2280 NVMe drives up to 4TB and M.2 2280 SATA drives up to 2TB, next to 512GB of storage in the box. A Micro SD slot on a USB 2.0 bus covers slow bulk storage such as a music library or camera offloads.

Where does x4 help on an N100? Large file copies, game and app installs, big photo folders and virtual-machine disk images all move faster. Everyday browsing and office work will not feel it much, since four efficiency cores become the limit long before the drive does.

For a Proxmox or Docker host, fast storage is the upgrade that matters most after memory. VM disks, container layers and databases all hit the SSD with small random reads, and a full-bandwidth NVMe drive keeps the box responsive under that load. The N100 home server setups show which services benefit.

The full port list is generous for a case this thin:

1. 2× HDMI 2.0, each driving a 4K screen.
2. 1× USB-C 3.2 Gen2 for power in, 4K video out and data.
3. 2× USB-A Gen2 for fast drives and peripherals.
4. 1× USB 2.0 for a keyboard or mouse receiver.
5. 1× Micro SD slot.
6. 1× gigabit RJ45.

Together the two HDMI ports and the USB-C port give triple display, the N100's maximum. A one-cable desk is the neat trick: plug the Overclock 4C into a USB-C monitor that supplies 36W or more, and that single cable powers the PC and carries the picture. Add two HDMI screens for a three-panel setup.

The gaps are networking and wireless detail. The Ethernet port is gigabit rather than 2.5G, and MeLE's description of the Overclock 4C does not specify the Wi-Fi generation. For a wired desk or a gigabit home network, neither is a problem.

The case itself won a Red Dot design award, and MeLE certifies it for FCC, IC, CE, UKCA, PSE and TELEC, which covers the US, Canada, Europe, the UK and Japan.

What a fan changes in practice:

• Sustained load: a fan moves heat away faster than a passive case can, which helps the N100 hold its turbo clocks through long jobs such as compiles, transcodes and big exports.
• Case temperature: an actively cooled case stays cooler to the touch than a fanless one under the same load.
• Noise: quiet at idle, audible when the chip works hard.
• Maintenance: a fan collects dust over the years; a passive box does not.

Memory is 16GB of DDR4 at up to 3200MHz. That is the amount an N100 wants for Windows 11 with a browser, an office suite and a video call open together, or for a few containers on Linux. MeLE does not describe a SO-DIMM slot in the Overclock 4C's thin case, so treat 16GB as the long-term figure.

Good jobs for the Overclock 4C include an office PC for two or three screens, a portable desktop that runs from the laptop charger in the bag, and a small homelab node that benefits from fast storage. Poor jobs are the usual N100 ones: gaming beyond light titles, heavy video editing and anything that needs a discrete GPU. The N100 gaming limits spell out what runs.

For silence, the fanless N100 options are the better path. The Overclock is for buyers who prefer steady clocks to zero noise.

The MeLE Quieter 4C is the pick for a silent room, at the cost of a case that runs hot and fixed memory. The MOREFINE M10 adds Wi-Fi 6 and 2.5G Ethernet but stops at two screens and 12GB. The Beelink Mini S12 Pro adds 2.5G and four 10Gbps ports in a thicker box without USB-C.

Of the four, only the two MeLE machines take USB-C power and drive three screens, and only the Overclock pairs that with a full x4 SSD slot and a fan to hold clocks steady. That makes it the most complete slim desk PC in the group. Its weak spots are the gigabit port and an unstated Wi-Fi generation, so a buyer who needs fast wireless should confirm the radio before ordering.

Choose the Overclock 4C when:

• Full-speed NVMe storage matters to your workload.
• You want to power the PC from a USB-C monitor or laptop charger.
• A quiet fan is acceptable in exchange for steadier clocks and a cooler case.

The whole MeLE range, from the PCG02 stick up, sits in the MeLE N100 line-up.
