I've got an old Antec 300 case that has done me well for many years (And was a recommendation from hexus!) and I'm looking to OC the 3570k CPU in it soon and was considering upgrading the stock cooler to a new tower cooler (probably a hyper 212 EVO) but was worried about fitting such a heavy tower cooler without having a motherboard tray cut out to help install the cooler. The last tower cooler I installed in this case was hard to do (I ended up dropping the MB into the case while screwing on the cooler - thankfully this didn't damage the motherboard but has left me concerned about doing it again and that was a smaller cooler). Should I consider a case upgrade while I've got the motherboard out? I've had a quick look and the corsair 200r looks ok or would I see little benefit with the new case (I still love my 300) or would a simple 120mm closed loop water cooler (and new case fans) be easier to fit in the current case? Total budget is about £80 but I'd rather spend less... If a new case is a good idea which case would you recommend?
Current equipment in the case:
Gigabyte z77-d3h (ATX)
16Gb Crucial ballistix elite (with large heatsink)
Antec semi-modular PSU
2x SSD
2x HDD
2x ODD
580GTX (considering replacing this sometime this year with something similar sized - unlikely to need SLI support)
ASUS Xonar PCIx soundcard
4x 120mm Antec fans
1x 140mm Antec fan
Ideal features in case:
No window (don't like them)
Prefer clean/functional look (like the Antec 300/200r) - definitely nothing to OTT
Good airflow
Easy to build
If keeping the current case should I clean the old fans or replace them?
Thanks.
