"Some negatives about rolling my own:
- Management: I won't get the special business features offered by some manufacturers. Dell's OpenImage, for example, looks awfully nice. But how much does that really buy me in a company of 60 machines? I don't use such stuff now; am I missing out on nirvana?
- Time to build: Even though we'd leverage Ghost wherever possible, handmade systems nevertheless take time to build, load, & configure.
- Supporting different platforms: Because money is so tight, I can at best afford a capital replacement rate of 25%-33% (15-20 units) per year. That means I'm committing to the support of 3 or 4 different platforms. Having just one platform is great, but how many companies, even ones that actively strive for it, truly enjoy that luxury? I inherited two platforms (Micron & Gateway); support isn't that bad. With proper planning, I don't see why we can't support four.
- Hardware quality: How much can I trust a popular Athlon chipset in a business environment? I feel silly bringing this up because I have a few Athlon systems at home, each with a different chipset, and they've been nothing but rock solid. But I know the lack of a really good chipset has been a large contributor to why AMD's aren't more prevalent in the business world. (well, that and long term bullying by Intel).
- I don't get a proven, prepackaged system that works right out of the box.
- Cost savings. Plain & simple.
- Increased horsepower per dollar spent.
- By choosing my own equipment (mobo especially), I suffer fewer OEM shortcuts.
- I have to admit that I'd enjoy the pure geek satisfaction of rolling out 'my' creation to the company.
