You could get a very nice CPU only setup for between $200-300. Heres what I suggest:
CPU Block:
D-Tek Fuzion $64.99
Radiator:
Swiftech MCR-220 $40
*This is where it can get tricky. You'll have to find a place where the radiator can get fresh air. If not inside the case, you must mount it outside. This can help out:
Swiftech Radbox.
*If you want to add a GPU block in the future, the
MCR320 would be a good choice if you can fit it.
Pump: MCP 655 $80
Reservoir: Swiftech MCRES $20
*I would personally get 2 additional high flow barbs just because the stock ones are a pain.
Tubing:
MasterKleer 7/16'' AND
1/2''
*I personally prefer the 7/16'', but its harder to get on. Looks better and has tighter grip. I would suggest you get 8ft of each.
Clamps: Worm Drive Clamps
Additives:
IF you want some color get this and follow the instructions:
Pentosin G11 $4.50
IF you just want some anti-algae colorless substance, use this and follow instructions:
PT Nuke $2.50
*ALWAYS use distilled water to dilute!
FANS: This is a personal choice, But I would go with the Yate Loon D12-SL or SM from
Petras. Choose SL for quiet.
We'll there you go, I tried to lay it out as simply as possible. If you have any questions, feel free to ask, its really easier then it looks.
