I suggest you to use serverhousing with forpsi.com, They are in Prague. If you're from Czech there is no prob for you to place machine there. Also it's probably the cheapest way to get your machine connected for 27.75 Euro/month, if you'll consume only 100GB/month bandwidth. The support is not very good but it's your machine so it's up to you.
I was with them for about 1 year. Then I moved to ThePlanet and pay much more now But you cannot compare services of both. There is a big big difference.
