28 Best Prime Day deals on PC parts 2021: Everything you need to build a great rig

This slim and compact case from Thermaltake has everything you need for budget-friendly PC builds. The sleek design and tempered glass panel offer a premium look and this thing looks far more expensive than it really is, especially on Prime Day. You’ve got the usual features like dust filters, PSU shroud, HDD drive tray, support for motherboards up to Micro ATX, and space for a 280mm rad upfront or at the top.

Mesh up your life with the NR600P from Cooler Master. This is one special chassis, supporting dual CPU motherboards, hot-swappable drive bays, and even a card reader upfront. The pre-installed dual 140mm intake fans on the front will pull in plenty of air to cool everything inside, but you can go all-out with water cooling if you’d prefer.

Don’t want the NR600P in black? There’s always the white TD500 right here, which has a similar mesh intake, but has space for three 120mm fans to really ramp up the cool air intake. The massive side window is glorious for showing off all your case internals, which supports up to a full-size ATX motherboard.

Want to build small? Good choice! Compact PC builds can be as powerful as larger systems but can cost a little more thanks to needing to choose specific parts. Luckily, Cooler Master’s NR200P SFF chassis is on sale for Prime Day and there’s plenty to like about this case. It even has support for custom water cooling loops.

With space for up to seven fans (yes, seven!) inside the Cooler Master NR200P, you’ve got more than enough cooling headroom for powerful PC builds. If you want to go down the custom route, Cooler Master even provides a pump installation bracket for custom loops. It’s a crazy good chassis for a capable compact PC build.

The Cooler Master MasterBox Pro 5 ARGB is all about style. The impressive-looking glass panel upfront sits just in front of the three pre-installed RGB fans, but there’s also a secondary panel on the side so everyone can gaze inside your build. Up to six 120mm fans can be installed in total and you can easily fit a 360mm radiator inside for strong cooling.

The NR200 from Cooler Master is the same as the NR200P, but without the choice of a tempered glass panel. It’s designed as more of a sleeper PC with a sleek finish that can contain far more firepower than the external chassis may lead you to believe. You’ll be able to enjoy the same number of fan mounts, water cooling support, and other highlight features.

White is the new black for PC cases and the NR200 is no different. You can find both models on sale for Prime Day, offering the choice between a bright or dark finish. So long as you don’t mind using ITX and SFX parts, you’ll be able to create a very capable gaming PC inside a chassis that’s barely larger than a console.

There’s a lot to love about the Thermaltake Tower 900. It’s expensive, huge, heavy, and cumbersome, but this also provides ample space inside for even the most ridiculous enthusiast PC builds. Want to go all-out with a multi-GPU and CPU water-cooled PC? That’s entirely possible with this behemoth.

The AMD Ryzen 7 3700X is a brilliant processor at this discounted price. Sporting eight physical cores and 16 processing threads, it’s more than a match for even the latest and most demanding PC games. The best part? AMD bundles a really good CPU cooler with the 3700X, so you’re ready to go from the get-go, and it supports PCIe 4.0.

Intel’s Core i7-10600K may be from a previous generation, but it’s still worth considering if you don’t need the best performance available from Intel. It’s a great little chip for gaming and would work just fine with our Intel motherboards highlighted above. Six cores with hyperthreading make this a beastly processor with clock speeds of up to 4.8GHz.

The Intel Core i7-10700K is a brilliant processor, especially for gaming and productivity. This chip houses eight physical cores (with hyperthreading) that can hit clock speeds of up to 5.1 GHz. When you’re not after the latest (and not-so greatest) from Intel, the 10th Gen series is a solid place to start.

This 8-core processor has 16 threads in total and can hit a maximum clock speed of 5.00GHz. The 16MB cache and support for Intel 300 series chipsets make this Core i9 a good upgrade for those on older Intel motherboards. If you’re still using a 9th Gen Core i5 or i7 and need a little bit more performance, look no further than this chip.

Should you not be interested in Intel’s 10th or 11th Gen collection of processors or wish to save a little on choosing older parts, the Intel Core i7-9700 is a brilliant processor for a gaming PC. It has 8 cores, 16 threads, and can hit speeds of up to 4.7GHz. You will need to pair this processor up with an Intel 300 series motherboard.

There aren’t always graphics cards available on EVGA’s B-Stock page, but when there are they offer some of the best value around. B-Stock is EVGA’s way of saying “Refurbished,” so this section features cards that have cosmetic damage or have been used before. They usually come with a 90-day warranty instead of a full warranty. Plus, while already being offered at reduced cost they sometimes come with even better deals.

80 PLUS Bronze certification makes this PSU up to 88% efficient while in operation, generating less heat and reducing overall energy costs. Corsair makes some killer power supplies and the CX650F with its smooth fan curve is a solid addition to any PC. There’s even smart RGB lighting, should you want such a feature on your PSU.

This is a super-affordable PSU, but it comes from the reputable brand EVGA. Usually, you’d find 80 PLUS White or no certification at this price point, but EVGA managed to work in 80 PLUS Bronze with up to 85% efficiency. The single 12V rail and active power factor correction ensure the PSU supplies stable, reliable power to the PC.
