I looked at ABS when shopping for a new computer, but I decided to order from NuTrend (
www.nutrend.com) instead, because it was somewhat cheaper and also received good reviews from mags such as PCWorld. I don't know if nutrend is still cheaper, though, as both companies seem to have completely revamped their product lines since I ordered mine in September. I have been pretty happy with the system, there hasn't been any major problems. They're probably faster, now, too, since they offer a mobo with the KT266A chipset instead of the AMD760 that i bought. When I ordered at least, both companies offered almost identical components in their systems, it was strange. ABS looks like a good, reliable company, though, if you want to order from them.
Edit: Just looked and it seems that nutrend is still the cheaper choice.
