The single biggest performance jump for the HP 18E7 isn't the CPU—it's the storage. Swapping the original 500GB HDD for a SATA SSD, like a WD Blue SSD

The board uses a standard 24-pin ATX power connector and a 4-pin ATX 12V CPU power connector. This makes it compatible with most standard power supplies, though HP often ships these systems with 300W or 460W units. Cooling is managed by a standard 4-pin CPU fan header and at least one 3-pin or 4-pin system fan header. Summary for Upgraders
