Computer Case
Recommendation: Coolermaster CM Stacker (STC-T01)Price: $174 shipped
Overclockers tend to swap components at a dizzying rate, always looking for something that will run just a little faster or perform a little higher on a competitive benchmark. Since components are likely to be swapped a lot, a case should be as flexible as possible, providing for future components as well as those that you might use today. Cooling is also a huge concern for overclockers, so a case that provides exceptional cooling is also a plus.
The aluminum-panel/steel frame Coolermaster CM Stacker is a case that fits the bill for the overclocker. Not only does it support 11 5-1/4" devices, it also supports both standard ATX and coming BTX designs. The case comes with conversion instructions for mounting a BTX motherboard. You also get support for either one or two standard ATX power supplies, and up to 8 internal fans, in addition to a unique optional crossflow fan.
Coolermaster cases are still some of the best for build-quality that you will find anywhere, and the CM Stacker is the most flexible case design that we have even seen. Whatever your particular desires in overclocking your system, you are likely to find a way to do what you need to to do with the CM Stacker.
You have to see the flexibility of the CM Stacker to believe it.
Power Supply
Recommendation: OCZ Power Stream 520WPrice: $130 shipped
The first thing most overclockers learn is that the power supply does matter because the first wall most overclockers run into is the inadequate power supply that came with their white-box computer. Overclocking demands much more of a computer system than running the system at stock speeds. If you think a Prescott at 3.4Ghz demands wattage, then you realize quickly that a Prescott at 4.0Ghz demands even more power. The same is true of video cards. If a 6800 Ultra Extreme demands a decent 470W power supply, then you will need even more power when you overclock that 6800 Ultra to higher GPU and memory speeds.
You also learn quickly that all power supplies are not created equal. Most power supply ratings are combined ratings, as regular readers have learned in Power Supply reviews at AnandTech. This means that as some of the power supply rails are driven, other rails drop in power, and may end up supplying less than ideal power under stress. The very best power supplies individually control the power rails. They, therefore, usually handle the stress of overclocking much better than a PS with a combined rating. These are the power supplies that are most coveted by overclockers.
A superb example of a power supply geared to overclockers is the new OCZ Power Stream 520. It was designed from the ground up for overclockers, and features individual rails that are even tweakable for higher output or exact values. There are even LEDs on the rear of the black chrome case that tell you if the PS is operating in spec, under spec, or over spec. These same LEDs can even be used to tweak individual rails for optimum power.
520W sounds like a lot of power and it is, but truthfully, this power supply would probably be rated at 700 watts by a manufacturer who was trying to impress with specs. The 520W rating is conservative and this PS can easily handle almost anything an overclocker wants to throw at it. While the OCZ Power Stream are new to the market, they have quickly become favorites of the extreme overclocking community.
You will also find a stock 24-pin ATX power connector that will work with the new Socket 775 motherboards and servers, as well as a 24-pin to 20-pin adapter to use with motherboards requiring a standard 20-pin connector. There are also extra long SATA and 4-pin Molex connectors to power anything you might put in a full tower case or the CM stacker, as well as special heavy duty cables for the demands of hard drives and the latest high-end video cards. You can find out more about the Power Stream power supplies at the Power Stream product page.
Alternative: Antec True Power 480W
Price: $89 shipped
If $130 for a top power supply seems a bit rich for your budget, there is a very good alternative with the Antec True Power 480. The True Power series feature individually powered rails, unlike the lesser Antec power supplies, which brings excellent stability to power-hungry overclocking.
The True Power series, in particular, is one of the most trusted power supplies among enthusiasts, and it will provide your overclocked system with stable power and some reserve for more overclocking. While a good quality 350W or 400W power supply might do the job for processors and video cards at stock speeds, you will definitely need a high-quality power supply like the True Power 480 if you plan to overclock.
If you cannot find the lowest prices on the products that we've recommended on this page, it's because we don't list some of them in our RealTime pricing engine. Until we do, we suggest that you do an independent search online at the various vendors' web sites. Just pick and choose where you want to buy your products by looking for a vendor located under the "Vendor" heading.

Perfect timing and very infomative article. I'm looking to buy a MSI K8N Neo2 Platinum w/ an AMD 64 FX-55 cpu.How would Crucial Ballistix PC4000 2.5-4-4-8 compare to PC3200 2-2-2-5 on the MSI mb? Faster bandwidth ver tighter timings?

Thank you, Fink.I ran Athlon64 Mobile 3200 2.0@2.55 Vcore 1.8
I will drop to 10x250 vcore1.7 for safer :>
Ballistix run@ 1:1 2.5-4-4-8 (I don't want to set 2.5-3-3-5 like the review for make sure that it works fine)
I'll tell the testing result again.
P.S. I had reached to 10x260 V1.8, windows works but Prime95 doens't work stable.

Wesley,If Raid 1 is used (mirrowing), is the slow down negligble for a simulations gamer - or would it be noticable? Would the same be the case with 7,200 rpm SATA's?
I also notice that you listed the eVGA 6800, but the July High-End Guide listed the Gigabyte 6800 (Ultra). Have you noticed performance or manufacturing differences between the 6800 vendors?
The photo of the Crucial Ballistik PC3200 512 memory has a CL113V.X1 part number on it. I can't find that part number listed on the Crucial web site. ? Bill Mackay

This is one interesting article, but I wish it had the same idea of a "Value" system as other AT articles. The Value system of this guide is too much for me, here's what I came up with:AMD Athlon XP Mobile 2400+ 45W $77
ASRock K7V88 Raid $44
512MB (1 X 512MB) Corsair Value Select DDR400 CAS2.5 $79
128MB GeCube Radeon 9550XT $99
Antec SLK3700-BQE Black ATX Midtower w/ 350W PSU $90
Seagate 80GB 7200RPM SATA (8Mb Cache) – ST380013AS $71
HSF not included, total of $460.
One could change that system to a Chaintech VNF3-250 + Sempron 3100+, but I would rather upgrade the video card first.

#25 Wesley Fink- its great to hear a Value RAM roundup is being planned, listening to and where necessary addressing your readers comments is one of the main reasons AT is such a valuable website.Gholam - Saturday, September 18, 2004 - link
You have a mistake on page 13 - you list CM Stacker as an all-aluminium case, while it definitely isn't. It has aluminium panels, but the chassis frame is made of steel. It also weighs 14.9kg... ouch. On the other hand, there is no other case where ducting the PSU is as easy...Wesley Fink - Saturday, September 18, 2004 - link
#24 - I mentioned in the Value conclusion that you can cut $300 by choosing a cheaper case and an ATI 9800 PRO instead. Perhaps I should make those recommendations part of the Value OC chart in the future.#22 - I recommended one 512MB stick of Crucial Ballistix to get the cost down on the lowest priced system and still have great overclocking. We do plan a Value RAM roundup in the future.

Wesley,Keep up the good work!
Only nit is that like last time, you "forgot" (maybe it was intentional) to present a value video card. The price of the video card stuck out like a sore thumb in the summary pricing table for the value system!
The power requirements are ugly, but consider putting the 9800pro in the summary table for the value system next time. Until the X700XT and 6600GT's come out (and in AGP), you can't do better for $190. [Or at least you could have downshifted from a 6800GT to a 6800 to save a hundred bucks on the value system.]

you know what would kick arse? doing comparison tests! Compare all the different rigs you guys reccomend and see who the winners are. i.e. Performance OC vs your high end setup etc.PrinceGaz - Friday, September 17, 2004 - link
I really don't know why anyone here is so keen on the Sempron 3100+. You'd be a fool to buy one when the A64 2800+ is available at only a slightly higher cost, has twice the L2 cache, and most importantly 64-bit support. Anyone who buys a Sempron 3100+ today will regret it in a year or two when x86-64 Windows is supported.If you only keep a CPU for a year or so though, it makes even less sense getting something like the Sempron 3100+ with hopes of high overclocks unless you like always having an overclocked substandard processor.
The non-high end memory issue is important and really needs to be covered, CAS 2.5 modules form the likes of Corsair are available at very competitive prices compared to CAS 2 modules. We need an article that looks at CAS 2.5 and also CAS 3 PC3200 modules from the major manufacturers so we can see how far they overclock, and at what voltages and timings. Most people don't buy CAS2 modules unless they're getting a top of the range CPU (2.4 GHz A64 or 3.2+ GHz Prescott), so if you look at an A64 3200+, you need to look at the memory most people will use with it.
