It's possible to complete your build and get to gaming with nothing more than the previous-mentioned components (along with a thumb drive for your operating system). The number of downloadable programs has increased to the point that many of our readers never need an optical drive (CD, DVD, BD-ROM). Cases come with mounting screws and usually include cooling fans. Most retail-boxed CPUs have a heat sink and fan. And a majority of motherboards are bundled with cables.
For other enthusiasts, the ability to run old programs or play media is critical. Overclockers, especially, will immediately toss aside whatever thermal solution their multiplier-unlocked CPU came with in favor of something more effective.
Even the most tight-fisted builder should be able to afford a DVD writer, with typical online prices ranging from $20 to 40 on the latest models of many popular brands. Blu-ray writers are more expensive, though not nearly as bad as they once were. Combo drives with Blu-ray read and DVD write capabilities used to fill the pricing gap, but that market shrank as the gap decreased.

Other power users prefer additions like a premium sound cards or TV tuners, though integrated sound is quite good nowadays and Internet-based streaming services make TV cards largely superfluous. Then again, that's what makes the PC so great. You have the freedom to swap parts in and out as your needs change.
The debate over optional or mandatory upgrades heats up when we get to the world of overclocking.

CPU coolers range from tiny devices as small as a 2” cube to enormous liquid-cooled radiator systems. We review the entire range, and think that first-time builders who would eventually like to overclock will have the most success with something that’s easy to install. Depending on your case, that could still give you dual-fan sealed liquid system or big air options.
Any of these items are optional for most builds, so let’s get back to the mandatory steps.
- Step One: Size Up A Case
- Step 2: Select Your CPU
- Step 3: Select Your Graphics
- Step 4: Select A Motherboard
- Step 5: Select Memory
- Step 6: Select Storage
- Step 7: Select A Power Supply
- Other Components
- Step 8: Choose Your Vendor
- Step 9: Preparing For Assembly
- Step 10: Build The Platform (CPU, Cooler, And DRAM)
- Step 11: Install Motherboard And Power Supply
- Step 12: Install Cables, Cards, And Drives

Wonderful as usual toms.. Appreciate it..
Great article! No doubt this is going to help a lot of folks.
Thanks, guys!
I think you missed a section for "SLI - XFire", but it's great overall. Since its a guide for folks with little to no knowledge, I think it would help them to dispel myths and get some facts over XFire and SLI.
Cheers!
First I put the motherboard into the PC (not fastened) to see where the standoffs are going to be placed onto the case. Also I note what routes I'm going use for my cabling. Then I take the motherboard out and insert the standoffs and port plate into the case. Also I take my case cables (power sw, reset sw, USB, front audio and mic cables and put a twist tie around them all and place them near where they are to be plugged into the motherboard. These cables are easy to lose track of.
Next I place the power supply, and "bay devices" (optical drives, non-removable storage, etc) into the case and have those cables attached and either hanging over the outside of the case or routed behind the motherboard tray. This obviously depends on how you determined the cables will be routed earlier.
Then I take my motherboard, put the CPU, RAM, and cooling system on as much as I can. Then I place the whole thing into the case - usually at an angle at first, leading with the side with the RAM (which is normally going behind the case bays in smaller cases) in first.
At this point it's just a matter of aligning the motherboard with the standoffs and port plate. Plug it all in (including the case plugs which are conveniently out of the way and together).
Power it all on and volia!
Otherwise, it was a good article. People who are uncertain of building their own PCs can learn a lot from it.
The 647W is measured at the wall socket, as the article mentions input power. After taking into account the 85% efficiency of their power supply in this example, the PSU is only outputting 549.95W to the PC components at max load. Adding some headroom they come to the 600W PSU recommendation.
Personally I'd like a little more headroom, but the calculations in the article are correct.
Building your own is great fun, and most serious users should probably give it a try at least once in their lives. Given that, I'd recommend an annual "refresh" of this article, with updated info and re-validated links to corresponding reference articles and resource forums.
A great service to your readers!
I wanted to comment on the power supply part of the article. One is the efficiency and the total cost to use versus the front end purchase cost. A less efficient system will obviously create more total heat as wasted energy. But aside from possibly making someones room rather uncomfortable, it also increases your airconditioning energy use. A good rule of thumb is that an AC system will use 50% of the heat energy. To add the total annual cost, multiply that times the percentage of the year that the AC is on. So your example of a 647W system with 85% PSU would give (550W used):
647W - 550W = 93W at plug
93W * 50% = 47W AC energy
Total Energy (summertime) = 93W + 47W = 140W
If the AC were on the while year and the PC were on continuously, this is about $140 annually, or almost $12 per month added electricity in the summer. If you did the same thing with a cheap 70% efficient system, you get $248 annual cost which is $20.63 per month summertime cost. At a difference of $8, it does not take many months (of continuous on!) to make the more efficient PSU make much more sense.
The other topic I wanted to comment on is ESD. I am an engineer and work with ESD issues everyday. It is a very real an poorly understood issue by many because of the often hidden or delayed failures that it causes. ESD many time causes walking wounded damage without an immediate failure, which finally fails several months later. And if you look at websites sell PC parts, many people complain of DOAs. Many, many DOAs are caused by ESD. Memory, CPUs, motherboards, HDDs, and other sensitive systems are often returned as DOA, driving up the cost of the PC enthusiast market and adding frustration. In research texts, they estimate the global electronic failures due to ESD to be 40-60% of the total failures over product life.
So that little $5 ESD wrist strap is money well spent. Buy one and reduce your heartburn.

The only problem with wrist straps is that most people don't want to be "tied" to anything. They're a great idea that's really rarely needed. Feel free to say otherwise if you live in the desert.
