With a desktop PC, you don’t have to shell out for a brand new PC just because you’re RAM or disk storage requirements have increased. Bought a NAS equipped with 10GbE support for your growing business? Install a 10GbE network adapter to take advantage of your new storage device. Looking for a speedy storage subsystem to gain the maximum benefit from your souped-up network storage? Add a fast solid-state drive or even a RAID 5 volume if there is sufficient space in your desktop chassis. And if there’s not, you can upgrade to a bigger chassis.
You can easily upgrade a desktop PC as your needs increase.
