Dell Dimension 8400 vs. Optiplex GX280 (ATX)

I do IT support for a department at a medium-large university, and we're at our year end, so, as the budget goes, we needed to spend the remainder of our surplus. We need a new student workstation, and we're under contract with Dell, so I recommended an 8400 b/c it uses the P4 6xx series, which has EM64T support and features EIST. We put in a requisition for the 8400 per my recommendation, and some guy from our IT department (separate from where I work) said that he'd reconfigured our req. for something "faster" and "cheaper," meaning the Optiplex GX280. The difference at the time (two weeks ago) was $197 and a little change. My argument was that for an extra $197 we get support for one more version of Windows and a machine that uses less power vs. spending another $1000-1200 to replace the POS GX280 when they get a license for XP x64. The IT guy said that he wouldn't recommend the 8400 since it ships with 32-bit Windows (which is a total scam by Dell...all universities have their own site-wide licenses for Windows, so why not offer universities machines without OS's) and since IT won't "validate" XP Pro x64 until they get a license. Thus, we're not really "gaining anything."

I responded by basically saying that he just proved my point. We gain support for another version of Windows, which he just admitted IT is going to a license for and "validate" (just as they didn't validate any of the machines we currently use for XP SP2). There isn't a chance in hell of our university getting a license for Longhorn when it's 1st released (no hardware on our campus will run it), so XP x64 is the next logical step for the next few years. Thus, why not start purchasing machines with this in mind now that Dell offers regular, non-workstation, desktops with 64-bit support?

He responded yet again by saying that while he admires my urge to get the "latest and greatest," he's concerned about stability. I responded by saying that if stability were an issue, Dell, HP, Sony, and IBM wouldn't offer the P4 6xx as a platform.

He said he'd let my supervisor decide, and my supervisor, of course, went with my recommendation.

I'd just like to add that this is the same IT department that recently purchased about 50 ATX GX280's (the ATX version isn't even offered on Dell's Small Business site any more, only the BTX version, with better cooling and less noisy fans, is offered...so what does that tell you about how Dell values universities...they reserve leftover junk for them) that were to be used for training. These particular GX280's were ordered with SoundBlaster Live 7.1 PCI cards, which Dell charges an extra ~$45 (x 50 machines = ~$2,250), yet not one machine had speakers attached (why would you want 7.1 surround sound going on during a presentation anyway?). This is the same IT department that has ordered Dell Ultrasharp monitors (vs. their E series analog LCD's) with graphics controllers that only have 15-pin D-sub connectors (i.e. no DVI). This is the same IT department that has been recommending 1GB of RAM for everyone (including secretaries and clerks who use MS Office, check email, and surf the Web). This is the same IT department who joins users' desktops to domain controllers so their AV software and Windows are patched automatically (wow, you can't do that with a stand alone workstation, wait, yes you can), yet leave security policies wide open so that users (connected to network drives shared by multiple employees) can install and run whatever they want and are vulnerable to spyware, adware, and an infinite amount of malware.

So, what would have been your recommendation?

My recommendation: Get a new IT department.

Out of those two, I'd take the 8400, but I can't really decided since I haven't seen the specs and costs.

Summary of the differences -> the GX280 only comes with the P4 5xxJ series whereas the 8400 comes with the 6xx series (and, thus, EM64T and EIST); the GX280's fans are quite noisy (I use one at work myself...but not for long...my boss is letting me build my own AMD64 desktop, which costs about $400 less than the GX280 and $600 less than the 8400), and the GX280's have had documented hardware issues (I read a report somewhere...maybe news.com...that Dell's Taiwanese vendor for the heatpipe on the 280 only used 2 pipes instead of the recommended 3 thus creating overheating issues).

Me, too. But again, we're under contract with Dell. I'm going to kind of use this opportunity to build my own machine for work as a sort of proof-of-concept to my boss so that we just bypass IT altogether for future purchases (at least for our department). See, everytime you put in a req. for a new machine, IT must approve it, which is where my adversary came into play. However, if you do a custom build, you don't have to put in a req. (you just use a purchase card online or wherever), and, thus, avoid IT. I'm just concerned that I won't really have time to do custom builds b/c I'm always slammed with programming, Web design, getting rid of spyware, adware, and malware, database administration, report writing, troubleshooting hardware/software problems, you name it.

No, the 5xxJ series only adds on the NX bit for LGA775 chips. Only P4 F's (which are different from 5xxJ) and 6xx support EM64T (and 6xx adds EIST).

I've got a mess of gx280s here at work, I'm on one right now... every one is dead silent. Actually I've never seen any of their optiplex machines that are even remotely noisy.

My gets rather noisy when my CPU usage goes up. It's an annoying mid-range frequency whine that fades in and out. The ones in that training room I was talking about aren't quite as bad, and they're newer. So maybe that's why. Either way, I still think the 8400 is the smarter buy.

If you have a lot of PC's to support you order the Optiplex, less image/hardware changes are made to the opti line.

Huh, what about the new BTX GX280 machines? They came out of nowhere, and going to a BTX motherboard, case, and PSU qualifies as a major hardware change to me. Before that, Dell went from the GX270 to the 280, which was s478 to LGA775, AGP to PCIe, and DDR to DDR2. Sounds like significant hardware changes to me. True, they've used the same ugly chassis since the GX2xx (I don't know how far they go back), but the same can be said for the fugly Dimension lines as well. The only real difference between the two is the Dimensions usually come preloaded with more crap like Dell Jukebox, Dell Media Experience, McAffee Security trial, AOL, Earthlink, etc., whereas the Optiplexes do not.
