The R3000T only has the equivalent of a Radeon 9200 (and it doesn't have its own memory, either). This is bad. Just on this basis, I would reject the R3000T. The G41, on the other hand, has the 5200Go w/64mb dedicated memory. If you are going to be playing any games, the experience will be much better with the 5200Go.
The WXGA is really sweet, and the wider screen will help you run things side-by-side. However, I don't know how big of a deal that is for you.
The 5400RPM hdd is a hell of a lot faster than the 4200. If you are developing software and going through compile cycles, this will make a big difference. Both CPUs are basically the same.
I know some people are making a big deal of going with A64 vs P4 because of software development. Honestly, unless you can find one for the same price and with the same features as these two, you will not see that big of a difference. Also, while the A64 is a little faster at compiling, the hard drive is the real bottleneck (unless you get enough RAM to run a RAM drive with all your files stored in memory).
Considering abf's proposal, I configured one of the Uniwill's at http://www.rayservers.com/catalog/pr...products_id=43
. However, the price came to ~$1500 for comparable specs. Obviously, I just picked the first buy who would let me buy it off of google. There might be cheaper prices out there.
Another point to take into account: warranty. At least for 1 year, so that you are covered.
