Bus, tiesiog nelabai ka idesi.. tau miniITX lyg ir neprivalomas, tada gali rinktis su PCIe 2.0 x16 slot'u:

Placiau: http://www.asrock.com/mb/Intel/N3150M/
- 1 x PCI Express 2.0 x16 Slot (PCIE2 @ x1 mode)
- 2 x PCI Express 2.0 x1 Slots

https://www.asus.com/Motherboards/N3150ME/
- 1 x PCIe 2.0 x16 (x1 mode) 
- 2 x PCIe 2.0 x1

x1 mode = pralaidumas nedidelis..

Siulyciau imt su N3150, o kai ateis laikas kazka daryt - pakeisi ta matke.. 
negausiai sita su N3150 kainuoja ~80-90Eur uz MB+CPU+VGA_Intel_8th_gen.
