When you build a PC, one of the first challenges is finding a case that works the way you want it to. NZXT’s new Lexa S is a $70 black mid-tower box (7.7 X 18.9 X 20.8 inches) with a stylized, angled front door that adds architectural appeal. But what’s most significant about the Lexa S is that, along with the usual plethora of 3.5-inch drive bays, it also includes a dual-disk 2.5-inch (laptop-size) drive tray that slides into one of those 3.5-inch bays.
The fact that that NZXT is supporting the smaller drive form factor is quite a big step forward. SSDs are currently offered largely for notebooks because of their 2.5-inch shock-proof storage and super-fast boot times. As someone who frequently needs totest computer components, I wanted a computer I could comfortably move around to my various testing stations (or even toss into a car) and not worry about jarring its disk(s) into extinction. In that case, native support for SSDs was a major plus.
And then there’s weight. When a computer is meant to be at least somewhat mobile, 2.5-inch drives — either SSDs or hard drives — can lessen the load significantly. For example, I installed a 640GB Western Digital Scorpio Blue 2.5-inch hard drive, which tips the scales at a paltry 4.2 oz. (In comparison, its 3.5-inch counterpart, the 640GB Caviar Blue, is a portly 1.39 lbs.) I then added a Patriot Warp 128GB SSD, which weighs 3.2 oz.
The result? The two drives added a combined weight of only about half a pound to the 15 lb. case instead of the nearly 3 lbs. that a pair of ordinary 3.5-inch drives would have added.
Converting to 2.5-inch drive bays
The Lexa S’s plastic adapter tray is a simple arrangement that’s built with two levels. One of the 2.5-inch drives sits on the bottom of the tray and is secured in place with screws from below the tray. The second drive sits on a pair of ledges at the sides of the tray and is held there by screws from the sides.
It took me less than 5 minutes to install both of the 2.5-inch drives. Two rails are pressed in place into holes in the tray, one on each side, so the tray can quickly and easily slide and lock into one of the case’s 3.5-inch bays.
If you need to, you can buy third-party adapters that will allow you to install 2.5-inch drives into most computers’ 3.5-inch bays. However, these adapters tend to be metal instead of plastic, they’re clunky, and when you’re done, it looks like you own an Erector set reject. NZXT’s adoption of a specific tray for its case is slick and useful.
Installing the rest of the components was a pretty standard process. I put in an Asus P5N-EM HDMI motherboard with an Intel Core 2 Duo E6700 processor. The motherboard comes with 2GB RAM installed and provides basic video via an NVIDIA GeForce 7100 chipset; it includes VGA, DVI and HDMI.
Because my computers tend to stay powered on around-the-clock, I passed on a stock fan in favor of a somewhat beefier (1.2 lbs) Thermaltake Silent 775 CPU heatsink/fan. I’ve had this one for a while (circa 2005); the closest currently selling fan is the Thermaltake Silent 775D.
A fan fandango
About the only problem I had with the 775 was that it nearly clashed with one of the case’s fans. The Lexa S includes three 120mm case fans in the back, front and side panels, and one 140mm fan mounted inside the top panel. The blades of that top fan came perilously close to the shroud on the 775’s fan.
The case includes five external bays and four internal 3.5-inch bays.
However, there was a solution: NZXT has built mounting accommodations for two fans on the top panel, one towards the rear and the other towards the front. The existing fan was at the rear, so I just had to transplant it to the forward mounting position. At worst it took two minutes.
I also installed a 5-lb. Antec NeoPower 480 power supply (you can’t buy a new one anymore but there are other NeoPower power supplies available in a variety of power ratings) and a Pioneer DVR-118L DVD burner (1.5 lbs.). Both of these were installed into the Lexa S using the supplied thumb screws. In fact, thanks to NZXT’s use of thumb screws, everything (except the motherboard) in this computer can be removed or swapped with another part in a matter of minutes without resorting to a screwdriver.
The case also includes five external bays (three 5.25-inch and two 3.5-inch) and four internal 3.5-inch bays. The motherboard adds two PCI slots, an x8 PCI Express slot and an x1 PCI Express slot; it supports six USB ports spread out between the rear panel and the side of the case as well as a side-mounted eSATA port.
Conclusions
What I have now is a desktop PC that I can carry around without much effort, test any card or drive I might need to when I get there and, thanks to the use of an SSD, will boot Windows 7 in 41 seconds and turn off in less than 11 seconds.
I’m sure there will be cases that accept 2.5-inch form factor drives appearing in increasing numbers. However, NZXT’s support for them now — while not compromising on card and drive expansion possibilities — is a major plus both for a PC used as a test bed and, inevitably, as we grow our computers from their first build to their final form.
