Rackmount Computers with Front Accessible Server
Rackmount computers can be the ideal workstation because the open slots could be used for one or more high-end video cards. Most of the units can now be configured to come with a 14-slot backplane and industrial-grade single-board computer, which typically gives users a selection and variety of slots to choose from. These slots may include ISA, SBC, and PCI expansion slots. Acnodes' compact sized units come with plenty of room for expansion cards, making it a good choice for stand-alone, data acquisition, controlling, and monitoring systems.

How To Identify PCI Express Vs PCI Expansion Slot?
PCI, Peripheral Component Interconnect, is a form of internal data bus for connecting or injecting peripheral devices into a computer. PCI is a general-purpose connection standard designed to support multiple devices of various kinds, including graphics hardware, audio hardware, network hardware, and such. PCIe, or PCI Express, is an interface for connecting high-speed devices to computers. The software is compatible with PCI but has greater potential bandwidth and larger flexibility than PCI. PCIe is used for internal Wi-Fi cards, 10 Gigabit Ethernet cards, hard drives, and Solid State Drives (SSDs).
