a single-core cpu, 1gb ram and a 80-gig hdd.
a 32-bit operating system.
the cheapest pricing for a dedi is at

. german site.
but i wouldnt reccomend you running a dekaron server. there are a lot of servers, it requires a lot of time, a lot of extra time and computing knoweldgements to add new stuff.
and the main problem: you will have NO income to pay the server. you'll have to pay t least 99euros montjhly with a minimum of 12 month contract time.
people from dekaron will not even donate you 1 cent.
