The HannStar K MV-4 (often labeled "K-MV4" or "K-MV-4") is a low-cost, compact motherboard commonly found in budget desktop systems and some OEM all-in-one PCs from the mid-2000s to early 2010s. The "94V-0" marking indicates the PCB flame-retardant rating (UL94V-0), not a model variant.
Hannstar is not a brand most gamers recognize, but it is a giant in the OEM (Original Equipment Manufacturer) world. HannStar Display Corporation is a Taiwanese company primarily known for manufacturing LCD panels. However, like many Asian electronics giants, they have produced or contracted the production of motherboards for mass-market systems—particularly for Compaq, HP, Acer, and various no-name white-box desktops sold in emerging markets during the early 2000s to 2010s. hannstar k mv-4 94v-0 motherboard
HannStar is a Taiwanese electronics company primarily known for display panels (monitors and LCDs). However, during the Socket 478 and early LGA775 eras, HannStar produced budget-oriented motherboards for pre-built systems (eMachines, Compaq, HP) and white-box PCs.
Replace if you need DDR3/DDR4 support, modern CPU compatibility, NVMe/SATA III, multiple PCIe lanes, or reliable long-term use; for basic tasks and low cost, refurbishing can be acceptable.
