Cases
Choosing a case is a subjective endeavor. We've listed some of our favorites below, and we recommend them wholeheartedly. That said, we acknowledge that not everybody will like their look or design as much as we do. To be honest, we don't mind folks following their hearts here, so long as they wind up buying something well-built from a manufacturer with a good reputation.

Buying a cheap, bare-bones case is one way to save a bit of cash, but it's not a very good way to do it. Quality cases make the system assembly process much more straightforward, thanks to tool-less drive drays, cable-routing amenities, pre-mounted motherboard stand-offs, and well-finished edges that won't draw blood. Quality cases tend to be quieter and to keep components cooler, as well. There's a whole world of difference in usability between a crummy $25 enclosure and a decent $50 one.

Budget

Product Price Notable needs
Cooler Master N200 $49.99 microATX motherboard
Corsair Carbide Series 200R $69.99 N/A

Cooler Master's N200 is a small and affordable case designed for microATX motherboards. It's more compact than the microATX Obsidian Series 350D we recommend in our Sweet Spot section, which means it's also a little more cramped inside. Nevertheless, the N200 is quite comfortable to work in, and its twin stock fans are a welcome feature in this price range.

Meanwhile, Corsair's Carbide Series 200R has been our favorite budget ATX enclosure ever since we reviewed it a while back. The thing is loaded with enthusiast-friendly goodies, from ubiquitous thumbscrews to tool-free bays for optical, mechanical, and solid-state storage. There's ample room for cable routing, too, and the stock fans are rather quiet. This is an ATX case that will accommodate any of the motherboards we recommended.

Fractal Design Define S $89.99 N/A
Corsair Carbide Series Air 240 $89.99 microATX motherboard, fan splitter
Fractal Design Define R5 $109.99 N/A
Cooler Master MasterCase Pro 5 $139.99 N/A
Corsair Obsidian Series 750D $149.99 N/A

Bridging our budget and sweet spot picks is Fractal Design's Define S, a TR Editor's Choice award winner. This ATX mid-tower features a completely open main chamber that's a pleasure to work in, and it's nearly as quiet in operation as the more expensive Define R5. Builders should take note of its limited room for storage, however: there's only room for three 3.5" and two 2.5" drives and no provisions at all for optical storage. If this case meets your needs, it's hard to beat in this price range.

microATX builders should check out the TR Recommended Corsair Carbide Series Air 240, a cuboidal chassis with a dedicated chamber for the power supply, hard drives, and SSDs. Despite its small size, this case is a delight to build in, and its dual-chamber design helps it run cool and quiet. Like the rest of the Corsair cases in this section, the Air 240 also has more intake fans than exhausts. That means positive pressure inside, which should prevent dust from sneaking in through cracks and unfiltered vents. Just consider adding a fan splitter cable to your shopping cart—some smaller motherboards don't have enough fan headers to manage the Air 240's trio of stock spinners.

For builders who want a more premium ATX mid-tower, we recommend Fractal Design's Define R5, which we graced with our TR Editor's Choice award. This case doesn't just look slick and stealthy; it's also a pleasure to build in, and it has great noise-reduction features. Fractal Design offers the R5 in black (with or without a window), titanium (also windowed or non-windowed), and white (fenestrated and non-fenestrated, of course).

A new contender between the Define R5 and Corsair's Obsidian 750D is Cooler Master's MasterCase Pro 5. This TR Recommended case is built with a highly modular interior that can be endlessly reconfigured to suit the needs of almost any conceivable system, and its heavy-duty, all-steel construction and stealthy looks don't hurt, either.

Between the arrival of the Define R5 and the MasterCase Pro 5, we're no longer recommending Corsair's Obsidian 450D at $129.99—it's a nice case that's been overshadowed by these newer designs. For $10 more, one can have the much more solid and versatile MasterCase Pro 5, and those on tighter budgets can get the Define R5.

Those competitors don't dethrone Corsair's Obsidian Series 750D, the luxury sedan of PC enclosures. This case is similar in design to the Obsidian 350D and 450D, but Corsair makes it big enough to accommodate E-ATX motherboards. The 750D is an extremely spacious case that's an absolute delight to work in. It's pretty darn quiet, too.

Cooler Master Cosmos II $319.99 A forklift

At roughly 14" x 28" x 26", the Cooler Master Cosmos II is humongous. At around $300, it's also quite expensive. This thing is unarguably impressive, though, with even roomier innards than the 750D and all kinds of premium features, including gull-wing doors, sliding metal covers, and a compartmentalized internal layout. We didn't give it an Editor's Choice award by accident.

Power supplies
This should go without saying in this day and age, but we'll say it anyway: buying a good power supply is a must.

Cheap PSUs can cause all kinds of problems, from poor stability to premature component failures. Also, many cheap units deceive with inflated wattage ratings. For example, a "500W" bargain-bin PSU might get half of its rating from the 5V rail, which is relatively unimportant, leaving only 250W for the 12V rail, which supplies most power-hungry components like the CPU and GPU. By contrast, quality PSUs derive most of their wattage ratings from the capacity of their 12V rails. That means an el-cheapo 500W unit could be less powerful in practice than a quality 350W PSU.

The power supplies we've singled out below are quality units from trustworthy manufacturers who offer at least three years of warranty coverage. Past editions of the System Guide have featured modular PSUs exclusively, but we've changed our thinking on that topic, at least at the budget level. Although modular cabling certainly helps to keep the inside of a PC less cluttered, the benefits are largely cosmetic. Folks without windowed cases may not need modular cables, and others may not be able to afford the perk.

At the same wattage, higher-quality PSUs with non-modular cables can often be had for only a little more money than lower-quality alternatives. While modular cabling is still a consideration, we've included some non-modular recommendations that trade convenience for better internal components and longer warranties.

We also tried to find PSUs with 80 Plus Bronze or better certification. 80 Plus Bronze guarantees efficiency of 82-85%, depending on the load. The higher a PSU's efficiency, the less energy it turns into heat while converting AC to DC power, the easier it is to cool quietly. 80 Plus Bronze, Silver, or Gold units tend to have large, slow-spinning fans that are barely audible during normal use. They'll save you a bit of money on your power bill over the long run, too.

Product Price Notes
Corsair CX430 $44.99 Non-modular, one 6+2-pin PCIe power connector
Corsair CX430M $49.99 Semi-modular, one 6+2-pin PCIe power connector
SeaSonic S12 II Bronze 430W $59.99 Non-modular, dual PCIe power connectors (1 6+2 pin, 1 six-pin)

Corsair's CX430 and CX430M kick off our budget recommendations. They tick all of the right boxes for entry-level systems: 80 Plus Bronze certification, 120-mm fans, and three-year warranties. They only have one eight-pin PCIe power connector each, but that's OK—even mid-range graphics cards like GeForce GTX 960 can often be powered with a single eight-pin connector.

For some reason, the inclusion of these PSUs in the System Guide bothers some people. We've made a sincere effort to figure out why, and we've come up empty-handed. The reviewers at JonnyGuru and Hardware Secrets both praise the CX430, and Legit Reviews likes the quality and performance of the CX430M. Ultimately, even if something was to go wrong with either of these PSUs, we'd rather buyers have the backing of Corsair's service and support than be left in the cold with a cheap, no-name PSU of dubious quality.

If the CX430 family bothers you for some reason, SeaSonic's S12 II 430W may be worth the step up. This PSU features Japanese capacitors throughout, and it has a pair of PCIe connectors—one six-pin, the other eight-pin. It also has a longer five-year warranty.

EVGA Supernova G2 550W $89.99 Fully modular, dual 6+2-pin PCIe connectors,
semi-silent mode
Cooler Master V750 $109.99 Semi-modular, quad 6+2-pin PCIe connectors
EVGA Supernova G2 750W $129.99 Fully modular,
quad 6+2-pin PCIe connectors,
semi-silent mode

PSUs aspiring to the Sweet Spot need to do more than the basics. We demand semi-modular cabling here at the bare minimum. 80 Plus Gold efficiency ratings should ideally be on the table, as well, along with semi-silent fans that spin down completely under lighter loads.

EVGA has expanded its superb Supernova G2 range to include a 550W model, so we're recommending that PSU for the first time. Like its bigger brothers, this is a fully-modular, 80 Plus Gold-certified unit. It's so good, in fact, that the PSU reviewers over at JonnyGuru gave it a perfect score. Consider us sold. EVGA backs this unit with a seven-year warranty, too.

In the middle of our sweet spot lies Cooler Master's V750. This semi-modular PSU provides a lot of power at 80 Plus Gold efficiency levels for a modest price. The V750 doesn't stop its fan during low-load operation like some fancier PSUs, but we'll accept that minor omission for the price. Scott has a V750 in the PSU bay of his new personal PC, and it's quietly powering twin GTX 970s without complaint.

For those who want something a little fancier than the CM PSU above, EVGA's Supernova G2 750W fits the bill. This 80 Plus Gold-certified unit features a fully modular design and a semi-silent fan mode. According to the reviewers at JonnyGuru, the Supernova G2's power delivery is practically perfect. EVGA is so confident in the Supernova G2 that it backs the PSU with a 10-year warranty if users register with the company, but beware: without registration, the warranty coverage is only three years.

For systems where 750W isn't enough power, EVGA's Supernova G2 850W unit is just as good as the 750W version above, but with extra wattage for multi-GPU configurations. If you're thinking about multiple GeForce GTX 980 Ti or Radeon R9 Fury X cards, this is your PSU.
