Who else is there?"
85% of the computers in the world are non-Dell. Looking at DELL only is like keeping the blinders on.
Intel just released 865 chipset based solutions in June. With a sluggish PC market, there is inventory glut of 845 chipset computers in channel that forces DELL to dump low end 845 solutions in expensively but mark up excessively on high end 865 solutions.
I would look either waiting till next year to get 865 chipset DELL system when they enter the mainstream at lower price point or go look for someone selling 865 chipset solution with motherboard from Intel with 3 year warrantee now that would be at about 30% less then Dell's current sales price.
I am configuring tonight for my own use a Intel desktop board D865PERLK that cost $150 and has hyperthreading support, 1 Gigibyte LAN, firewire on board, RAID 0,1, SATA-150 ports and 800 mHz front side bus combine withd $230 2.6 GHz P4 and $80 80 GB SATA hard drive.
