Computer Products for Sale at iNET PC Waukesha Computer Store:

CPU (Central Processing Unit)

A central processing unit is a piece of hardware within a computer which allows programs to function. CPUs are the most important component for adding speed and efficiency to common computers and if the CPU doesn’t work, nothing works. Whether you need a replacement CPU or one for a new build, head directly to iNET PC.

Computer CPUs for sale in Milwaukee


A motherboard is your computer’s main printed circuit board (PCB). It's essential for communication between all your PC components. Your motherboard needs to have the space for your CPU, graphics cards, RAM and PSU, and it pays to leave room for computer upgrades.

RAM (Random Access Memory) is the way your computer stores data. This computer component makes it possible for data to be read and written simultaneously. Having more RAM is crucial if you intend to run numerous programs at once or use memory-intensive software like photo editors, games and music production toolkits.

PSU (Power Supply Unit)

The PSU converts normal household AC current to the low-voltage regulated DC power needed by internal computer components. Each computer part requires a certain amount of power. The PSU provides the right amount. Nothing is more dangerous to your computer than a faulty PSU; if computer components get improper amounts of power, they'll short out.

Computer Towers

A nonstandard computer tower is a great way to have a computer built specifically to your spec. If you're an experienced builder looking for a custom system, we have the towers for your next creation. Our towers have room for everything you need, plenty of USB slots, and high-cooling or sound-proof systems. Most importantly, they look really cool. If you want our computer geeks to build a system from scratch, we'll do that, too.

Internal Computer Fans

Computers generate heat, especially the more powerful ones—which is why it's essential to have fans inside them to draw cool air in and blow warm air out. A fan that isn't working will cause your computer to overheat, damaging the internal components and cause unexpected shut-down. iNET carries quiet, efficient fans which minimize cleaning times. If you're really determined to never need to dust off your PC, consider a water cooling system.

SSD (Solid State Hard Drive)

A solid-state hard drive uses only integrated circuit assemblies for memory and has no moving parts, hence the name. SSDs are faster and less prone to failure than traditional HDDs (Hard Drive Discs), though they are more expensive. Using one to store your operating system, critical programs, or even your entire computer memory can dramatically boost your computer's speed. Most are compatible with traditional input/output (I/O) hard disk drives, so replacement is easy.

GPU (Graphics Card)

A GPU, or graphics card, is similar to a CPU but is specially built to efficiently run frequently repeated calculations, like those that create video game graphics. iNET carries GPUs that will give your favorite games a snappier, faster experience. GPUs are also important for some video editing and CAD programs.

Sound Cards (Audio Cards)

A sound card (or audio card) is a computer part to expand the internal input and output of audio from your computer programs. A sound card can noticeably improve the quality of your sound system, allowing you to enjoy movies or games in a more immersive way. Sound cards are also crucial for most music production PC builds.

Talk to our techs about adapter cards and how they can improve your computer.

PCI and PCI Express Riser Cards

"PCI” is short for Peripheral Component Interconnect. This computer component delivers data to and from your computer's CPU from peripherals like your PC's mouse, keyboard, monitor and speakers. PCI Express (PCIe or PCI-e) components are the faster and smaller version of PCI risers currently in use. They improve connectivity and speed.

RAID Array Controller Cards

RAID is an acronym for "Redundant Array of Inexpensive Discs." RAID arrays are far safer and faster than single disc memory storage, but they're only usable with a good RAID controller card to manage the discs and present their memory in a workable form to your computer.

CD-ROM Drive

CD-ROM is an acronym for "Compact Disc Read-Only Memory," the major data storage system of the early 1990s. iNET carries inexpensive and reliable external CD-ROM Drives so you can continue using your music collection, family photographs or other CD-stored content with any new computer.

A DVD (or "Digital Versatile Disc") is another digital disc storage format that was popular from the late 1990s to the late 2000s and is still common today. DVDs are, as the name says, versatile, and iNET carries DVD players that can read DVDs along with Blu Ray discs.

Blu-Ray Disc Players
