At 1K, you conldn't get everything you wanted out of it. Anyway your main concern would be the CCTV mode. Usually a PC which does CCTV has to be a standalone machine and not be used for other purposes. A regular off the shelf CCTV system requires you to have at least a TNT2 or Geforce graphics adapter. Which none of the bulit in cheap board offers. And you need at least a 160GB hard disk to work with in minimum of 2 partitions. CCTV recordings take up hard disk space!

Also notice that boards that share memory would be slower than that that has a graphics card. You definitely can't enjoy the CS with your budget. Even guys with FX5200 cards are grumbling.

Cheap boards also does not permit you to upgrade to higher memory capacity. You could get with 2 sticks of 1G memory. But still it would be slow.

In the end RM1000 is just not enough. My sugestion is this,

AMD X2 3600 - RM270
ASUS M2NPV-MX - RM315
Kingston 1G DDR2 - RM 250
Seagate 250G hdd - RM250 (partition 100G for usage balance for CCTV)
icute 450W ps & casing - 130
(Option) Geforce 7100GS Pcie vga card - RM150 (But bump to RM290 and you have a 7300GT!)

At RM 1215, at least your are somewhere close to your budget all in one rig. Even then the CCTV is a bother because everytime it records, it bogs down the system a little.

So is it a little clearer now?
