What are Case Accessories?

Case accessories are additional components and tools designed to enhance the functionality and aesthetics of your computer case. Different computer case accessories allow you to build, repair, and upgrade your computer. There are brackets and screws available to install various components, and replacement fan grills, dust filters, and wire kits offer upgrades and improvements to systems. LED strips, RGB controllers, colored brackets, and transparent side panels are suitable for decorative purposes while still catering to practical needs. Case accessories are available in a variety of styles, sizes, and colors to meet everyone's needs. Be sure to check the specifications of each component to ensure it will be suitable for your case's form factor (size).

Build Your PC With Computer Case Accessories

Building or upgrading your computer is easier with the correct PC build accessories. Use high and low-thread count screws to secure your parts inside the case, such as case fan screws, for example. Keep extra screws on hand for future upgrades or repairs. The StarTech.com PCSCREWKIT contains an assortment of screws, nuts, and standoffs in a convenient case. Install anti-vibration fan mounts, such as the Noctua NA-SAVP1 Chromax Fan Mount Set, to minimize noise. Use an HDD slot cover to keep cables from tangling. Find a GPU (Graphics Programming Unit) bracket for a gaming PC or to fit your HTPC media computer case. Organize and control your fans with a fan controller.

For an easy and hassle-free PC building experience, try Newegg's PC Builder tool to select and compare compatible components effortlessly.

Heavy-duty Case Accessories for Protection

Protect your fans with replacement fan grills. Reach the back of your computer and move the device around with a CPU roller. If your replacement HDD (Hard Drive Disk) is a different size, you may need to purchase a drive bay adapter, such as the SIIG SC-SA0H12-S1 3.5" to Dual 2.5"Drive Bay Adapter. Fit two SSDs (Solid State Drives) into one HDD cage like the be quiet! HDD Cage, or purchase an SSD rack. Consider installing a new dust filter to keep your components free from dust and other debris. Replace damaged wiring with hookup wire, and set up more SATA (Serial ATA) connections using an HDD/SSD hot-swap back panel, such as the one by Lian Li. Protect your computer case with rubber feet, and replace damaged LED cables with a power reset LED wire kit, like the one from StarTech.com. Close exposed slots using PCI slot covers.

Versatile PC Case Accessories for Gaming Builds

Display your components beautifully with lighting if you've purchased one of the gaming cases with transparent side panels. These tempered glass panels are available separately to install on your existing computer case. LED strips, such as the DEEPCOOL RGB 350 Computer Lighting Kit LED Strip, can easily add unique visual features to your system. Neaten up your wires with cable extenders, like the CORSAIR iCUE LS100 Smart Lighting Strip Expansion Kit or cable sleeves. If lighting isn't your thing, purchase cable extenders and sleeves in a color that suits the rest of your components. Use a vertical display VGA holder kit or vertical GPU (Graphics Processing Unit) to display your VGA (Video Graphics Array) card for aesthetics.
