Hi Illlumen,
Yes, take it easy, while saving money, you can play around with your rack and those modules and after a while you will see you get a more clear view on what you like and prefer, from there you can then see how you can "fill up" the HP-gap :-)
Have fun with your modular system and kind regards, Garfield.
