Comment by Max

addition to my previous question, I'd have 8GB of ram, would like to be able to upgrade to 16GB though.

Thanks, Max

Response by jonathana
you should still have the space
Corsair do some great RAM modules.

will it fit by Max

Will this case fit an ATX mobo running 2x MSI HD7870's with a H100i? also what PSU would you recommend with this set up?
The cpu is an i5 3570k + 2 HDD's, 1 SSD, MSI B75a mobo,Disk drive and a couple of case fans.

Thanks, Max

Response by jonathana
This case will fit ATX Mobo's, as for the PSU I always recommend a high one (600+), so even if it's all not used, you can still make upgrades and swap out components with a higher wattage usage without having to replace your PSU. Corsair and be quiet! have some excellent PSUs and coolers/fans. I would recommend either the Corsair CX (budget) or TX 750W
