The Technobox 7673 is designed to support a single M.2 device of standard lengths (30, 42, 60 and 80 mm). All are 22 mm wide. The default is 80 mm to accommodate the most common length for M.2 SSDs. Accordingly, retaining hardware is pre-installed at the 80 mm position. The 7673 allows up to Gen3 speeds with 4X lane connection to the M.2 card, with no intervening PCIe switch, unlike the Triple Site M.2 XMC (P/N 7971).
