before posting, the owner must own 1 full rack and get the price out. To be more accurate because some datacenter require you to get a full rack to get a discounts!
What I know in Hong Kong,
They provide "unmetered" transfers (on shared 100mbps international bandwidth...*note, sharing with more than 1x,xxx servers)
1U colocation $250HKD/month ($38USD/month)
This datacenter is already quite good one already
The worst datacenter which has just closed down...and is belongs to I-Advantage
1U colocation $56HKD/month ($7.12USD/month)
Includes 100mbits port "unmetered bandwidth" and "256kbits international bandwidth"
^^ awesome prices!!
