MicroATX or FlexATX mobo recommendations?

[indolering]

Anyone have a 4 slot PCI-express flex or micro ATX recommendations?

There is a cheap G5 case that I am looking to drop one of these into (excellent airflow design).  A normal ATX board requires a lot of modding.  I just want to drop and go

I have found a few, but they have been relatively expensive -near $200 with CPU.  I can get a complete rig for $275...
Thanks,

Do you plan on using risers at all ?

For mATX

1. Gigabyte H61M-D2-B3 (3 x1, 1 x16)
2. Gigabyte H67MA-USB3-B3 (2 x1, 2 x16)
3. Gigabyte Z68AP-D3 / Gigabyte Z68MA-D2H (1 x1, 3 x16)
4. MSI H67MA-E45-B3 (3 x1, 1 x16)

i think you really only need 2 pci-e slots on the motherboard, a mATX motherboard can only fit 2 double slot GPUs. why are you looking for a small mobo with 4 pci-e slots? unless i missed something

Use PCI-E Ribbon cables and custom built case. Cards can then hover far above the motherboard and have more than enough space between each card for ventilation. The only problem that may arise is each PCI-E slot is specced to supply 75W of power, and fully loading all slots may cause serious problems. You can get a PCI-E ribbon cable with a 12v molex connector wired into the ribbon cable to supplement the power to the motherboard, but they aren't exactly cheap.
