I'd say go for Asus,the 815 chipset is better then the 810.

I tried it before but for some weird reason it kept beeping and clicking while it was loading,and boot would hang.(Windows 98)
Any ideas why?Also,I heard 815 has 512MB limitation.Does this apply to the 810 too?

Acording to this they both limited to 512 mb,but the 815 has support for 133 mhz cpu's and support for agp.
As for the beeping,check if everything is corectly mounted on the mainboard,that all the jumper's and dip switches are in the corect position,check the memory with memtest.

I checked and not all 810 are limited to 100mhz.For example,810E supports 133MHz.
For the beeps,I checked everything.Basically the screen's power led turns green,I have signal and the board's bios starts up but all the while I have a continuous beep for a few seconds then clicks as if I kept pressed a key on my keyboard.(even though I didn't)

Damn.The CUSL2-C died.Oh well,all I can build now is a custom Netvista.Sadly,the network card I have isn't working.(IBM EtherJet PCI/Intel PRO 10/100 Ethernet or something like that)
Pictures are coming tomorrow.(9:48 PM here)I did a cable management too.
In the meantime,have the specs of it:
MB:Gigabyte GA-6WMMC7-E1(this means it has the 810E chipset,which has 133MHz)
RAM:128MB
Processor:Intel Pentium 3 800MHz (133MHz FSB!)
Sound:AC'97,as usual
Video:onboard,Intel 82810
HDD:Seagate ST310211A 10GB(from a Xbox original)
System:Windows XP Home Edition SP1
BIOS:IBM PTKT16A,even though the BIOS sticker said PTKT15A!
Here's pic.Kind of blurry,sorry.
