Motherboard Offers

WalmartAnd the Newegg ($185)

This motherboard is our choice as a starting point if you want to start a mid-level Intel-based PC. It supports LGA 1200 socket type, DDR4 RAM, and it also comes with built-in Wi-Fi, giving you one additional card in your desktop.

AmazonAnd the New

Another Wi-Fi capable motherboard, the ASUS TUF Gaming model similarly supports the LGA 1200 socket that supports both 10th and 11th generation Intel CPUs.


On the other hand, if you prefer AMD processors — and there are plenty of reasons to do so — this motherboard supports the AM4 socket for those CPUs. You can get an extra $10 off this deal at mail-in discount, just be sure to give it a try.


Another AMD-focused motherboard, the ASRock B550 Phantom gameboard supports the AM4 socket, but in a smaller Mini ITX configuration. This is more ideal if you want to make a computer that is relatively slimmer and less expensive.

CPU Deals

AMD Ryzen 9 5900X CPU

The Core i7 is part of the 10th generation Intel CPUs. It’s a mid-range solid CPU and compatible with LGA 1200 socket. This model doesn’t come with its own heat sink, so you’ll need to add one of them to your machine as well.


While this processor is slightly less powerful than the i7 above, it is part of Intel’s 11th generation, Rocket Lake CPUs. It still uses the LGA 1200 socket, so you can put this in the same motherboard as any of the other Intel CPUs we’ve offered.

AmazonAnd the New

For more power, this Core i9 CPU is part of the 11th generation Intel, but is still compatible with the LGA 1200 socket. Like the other CPUs mentioned above, it doesn’t include a heat sink in the package, but the discount you get on This wizard should help cover that.

AmazonAnd the Newegg ($495 with code BCMAY22639)

On the AMD side of the market, the AMD Ryzen 9 5900X is a powerful processor (and by standards, more powerful than the Core i9 above) that works with the motherboard’s AM4 socket.

Newegg (use BCMAY22642 at checkout)

Closer to the underside of AMD’s line of high-end processors, the Ryzen 7 5700G is down $40 right now if you use the somewhat cumbersome promo code BCMAY22642. This processor is inserted into the AM4 socket.

Newegg (use code 93XSD62)And the Walmart ($350)

This Ryzen 7 process has slightly better performance for a slightly higher price tag than the above 5700G. At NewEgg you’ll need to use coupon code 93XSD62, but at Walmart it’s a flat $350 with no code needed.

Memory Deals

Newegg (use NECYMTEN29 at checkout)

This pair of 16GB of RAM adds up to 32GB of 288-pin DDR4 memory. This should be more than enough to handle most daily tasks and even most games.

Newegg (use the code NECYMTEN29 at checkout)

If you don’t need the same amount of RAM for heavy-duty tasks, this pair of 8GB – 16GB total – of DDR4 RAM will be more than enough for light work tasks.

Newegg (use promo code BCMAY22389)

Another pair of 8GB sticks – 16GB total, the math is fun – this set is pretty much the same as the pair above. So what makes it worth the extra money? RGB lights built into the top, of course.

Storage Deals

Samsung 870 EVO SSD

Newegg (use promo code BFFRDY73)

Some modern motherboards have a slot where you can insert a compressed PCIe SSD drive, which offers massive speed advantages to your computer. This spacious 2TB drive can fit right into that space, if you have one.

AmazonAnd the best buy

Since SSD space can be pricey, one of the best ways to get speed upgrades without paying a lot of cash is to get a smaller SSD for your main drive and larger, slower drives for storing files. If that’s the way you want to go, an inexpensive 500GB SSD with plenty of space for Windows, as well as your most-used apps and games.

case deals

This mid-size tower enclosure can house ATX-size motherboards, has two 3.5-inch drive bays and a relatively neat glass panel on the side. In case you want to show RGB LEDs on your RAM.

Newegg (use promo code BCMAY22245)

For heavy PC builders, this full-size ATX tower from Lian Li features four 3.5-inch drive bays, a tempered glass side panel and even King RGB LED strip, just in case every component inside the enclosure doesn’t glow enough for you.

Newegg (use promo code BFCRTX8)

This mid-size Corsair ATX case comes with a quieter look, and also features tempered glass, two 3.5-inch drive bays, and a durable steel frame.

power supply offers

Thermal Tec Toughpower GX2.5

NewEgg (use promo code BCMAY22662)

The primary concern of your computer’s power supply is how much power all the other components are consuming. This Thermaltake power supply can put out 600W, which should be more than enough for most basic PCs, but you may want to start monitoring consumption if you plan on doing heavy work or gaming on it. You can get an extra $10 from this power supply by mailing in a discount form.


A step up from the previous power source, this Cooler Master model can output up to 750 Watts to your device. It also does not require any special postage discounts or anything to get the full discount.


At the higher end of the power supply bargains we’ve found, this Corsair one can handle up to 850 watts, which should be enough for most gaming PCs, even if you have a really high-powered graphics card. If you can get your hands on one, that is.

Other deals

NZXT BLD . Building

NZXT is a compromise between buying a pre-built PC and building one yourself. It’s one of our favorite options for buying a gaming PC, and right now the company is getting 10 percent off sitewide.

Newegg (use BCMAY22627 for $100 off, give $150 off)

Call this deal a bit of a misnomer, since the retail price of the AMD Radeon RX 6900 XT is $1,000. This is much more than that, because graphics cards are in high demand and display is low. This is one of the best discounts we’ve seen when benchmarked against the price of a particular card lately—and even this requires a mail-in discount for the bulk of the discount—but it’s almost more valuable as an object lesson for why waiting to find a graphics card might be a better option.


For all the above CPUs that do not come with their own heat sink, this liquid cooler unit can be a great choice. It’s one of our favorite picks for system builders, and yes, it comes with plenty of RGB LEDs.
