By, Me! ;)

The first thing I noticed when I picked up the box that the FedEx fellow left by my door was, ?This thing is light!? But, bear in mind, it does not come with a PSU, and I have only dealt with steel cases before. So, your mileage may vary.

I opened up the box, and the nice all aluminum from bezel looked up at me. It really is a good-looking case. But then again, I have only looked at those plastic fronted ?posers? before. I took it out of the box, and unwrapped it. I was eager to see if it really was ?tool-less? construction. I flipped it over to look at the back, and sure enough the two side panels were held in place by a pair of thumbscrews each. In between the four PSU screw holes are a pair of threaded holes on each side that housed their own thumbscrews for the PSU as well. From here, I looked at the back panel to see just how much work was involved with making my motherboard fit. I am sad to say that even this panel is aluminum. Thin aluminum at that. I think they could have left this one panel steel.

But I pressed on. To the right of this panel I saw the exhaust fan pressed grill. It was an ample ?bulls-eye? pattern, with an ?x? shaped support posts and three concentric circular holes that make up the grill. Not bad, but it would have to go when I had the time. Then I noticed my second disappointment. The stock case fan was press fitted in. There are four plastic, slightly oversized, pins that are just pushed into the screw holes. Ah well, just encourages me to upgrade the fans faster.

Now I am eagerly removing the thumbscrews to the left panel. I noticed there is a little ?key? panel that sticks out through the side panels back flange. I presume that is where you could attach a lock to prevent someone from opening the case?. But I do not see the point really. The panels are aluminum after all. A pocketknife could cut through them. But I remember when key locks on the power supply were all the rage. I figure this fad will pass as well.

Now the side panel is removed, and I am very impressed. There is quite a bit of space that greets you when you open this case. The motherboard shelf is a good size. No need to worry about the memory sticks getting in the way of a CD player here. (Like it is in my current ? soon to be ex ? case.) There is a nice sidewall the runs along the top, that drops down to just below the PSU on the back side, and curves around to the bottom of the 4 5.25? bays. There is a nice plastic safety sheath already in place. A nice touch. This sidewall is perfect for hiding all your wires up behind. There is even a nice big wire clip with an adhesive pad on it for just this purpose. It may make things a bit difficult for adding in a blowhole, but I do not think this case would require one. More on that if I find it necessary to modify the case that way.

Beneath the 5.25? bays, are the 3 external 3.5? bays. Beneath that is a removable shelf ? that has its own pair of thumbscrew ? that can hold 5 3.5? drives sideways.

It is about now that I realize that the case is not completely ?tool-less? as the ad I read states. The expansion ports are held in with normal screws. The drives do not have their own thumbscrews provided. And there are no additional thumbscrews anywhere. But I can live with out the thumbscrews in a few places. Besides my thick fingers would have a hell of a time trying to get a good grip on a thumbscrew holding an expansion board in. So it is just as well, as far as I am concerned.

Behind, and below, the removable shelf is a built in channel that you can run all the necessary cables along. There are two 80mm case fans mounted in front of the shelf that are press fitted in as well. The front case grills are a nice staggered pattern of holes, so from directly in front of the fans you do not see much of them. There appears to be about ½? between the front of the case, and the inside of the bezel. The front bezel seems to be held in with four, double prong, plastic clips at each of the far corners. So it would seem that putting a replaceable filter in between the two grills would be a difficult endeavor for a ?quick? chore. But I will have to play around with those clips and see just how difficult it is to reach all of them.

All in all, I am quite pleased with the case. I think it will do a fine job of improving my hot tamale of a motherboard/CPU combo. I will post more details after I make the transplant, and gather some data.

If I have missed anything you would like to know about, please ask the questions. I will try and answer as best as I can.

Of course! Sorry. I should have guessed that would be a factor to some people.

The stock fans have 4 pin connecters with "built in" bypass so you can plug them into a device.

There are no leads for RPM monitoring.

EDIT: I should also point out that the two front mounted fans are not wired together. They each have their own four pin connecter, with built in bypass.

Anything else?

Alright, after doing the actual case swap, I have learned a few more things.

1) The front bezel just pulls off. What I thought were the clips that I saw on the inside were actually the recepticals for the actuall clips.

2) The case side grill in front of the front case fans is removable, and inside that the case comes with a filter already installed. There is still room for another filter between the two grills, but I will wait and see if that is needed.

3) The external 3.5" shelf is removable as well. When you pull off the front bezel, there are three thumbscrews that, when removed, allow you to pull the shelf out of the front of the case.

4) What I thought were just the thumbscrews for the PSU, actually were holding in the removable PSU mounting plate. I have yet to guess why this is designed this way.... But I am leaning towards the easy swapping of PSU's?? I dunno.

I am now going to run the computer for about a day, and get temp. readings. I haven't switched out my CPU heatsink yet, so this will actually give a good idea of what the case can do for cooling.

I will report back in about a day to relay that info.

Okay. After running my comp in the new case for 24 hours this is what I have found.

All numbers are according to Motherboard Monitor 5

Previous case (unknown manufacturer) w/ side panel off due to previous heat problems.

Motherboard Sensor: 16c-19c Average 17c / 60F-66F Average 62F
Case Temp: 31c-34c Average 32c / 87F-93F Average 89F
CPU Temp: 54c-57c Average 55c / 129F-134F Average 131F

These temps are mostly at idle, with some surfing/mail reading.



Lian Li PC 7 Case, with the 3 case fans hooked up to the "Fan Only" leads of my Antec True Power 550w PSU (fully enclosed)

Motherboard Sensor: 14c-17c Average 15c / 57F-62F Average 59F
Case Temp: 29c-30c Average 29c / 84F-86F Average 84F
CPU Temp: 54c-60c Average 54c / 129F-140F Average 131F

These temps include some game playing, but mostly at idle.


It should also be noted that I could not play games before changing cases due to heat problems (I am assuming).

So, while the case and motherboard are nice and cool now, I am still having difficulty with my CPU.

Does anyone know if an unstable OS can cause the CPU to "overheat"? It would make some sense.... But I am curious if anyone has some hard examples of this happening.

Never heard of that happening.
What HSF are you using? Ever get that SLK-900?

I'm wondering if you have a heatsink-installation issue there. Two frequent problems are to reverse the heatsink, or to get it installed in the correct direction but to let it get jacked up on the solid end of the CPU socket. Refer to the guide in my sig, and if you have a heatsink that can slide around on its clip (such as Thermalright SK- or SLK-series, or a GC-68 style) then refer to this]http://home.comcast.net/~t.mcfadden/SK7-1.jpg[/L][/L] so your heatsink clears like this

The HS/F are both stock. I have had heat problems in the past..... But nothing like recently.

Changes that might cause the problem:

1) I have upgraded my Vid card to the Geforce 5900 Ultra.
2) Added a second HDD
3) Added a SB Audigy Xgamer card

All of these were 1-3 weeks before the new heat problems.

But.... After swapping cases, both of the other temps dropped about 2c-3c. Only my CPU crept back up to its current state. ((It started out about 2c-3c cooler as well, but after running about an hour spiked back up to it's current temp. And I have double checked the temp reading with the BIOS and with SANDRA, so MBM5 is as accurate as the motherboard is telling it.))

((Oh, BTW Slogun, yes I have the SLK-900. I have not been able to put aside the time I want to do the heatsink swap. I am also toying with the idea of getting a new mobo, so if I do I just want to swap the heatsink when changing the mobo.))

After some stress testing, details can be found here, I have narrowed down my culprit to my OS.

I thank Sunner and drag for assisting me in my analysis.

If anyone knows of a temp readout program that runs in Linux, I can even give readouts to help prove it.
